How Can an Ultrasound Scan Help You?

In today's society health care technology is advancing every single day. From CT scans to ultrasounds, health care professionals can easily detect potential foreign structures and even monitor the growth of a human baby. Usually health care providers can monitor the growth of a foetus by measuring a woman's uterus. However, there are also times when providers may order an ultrasound scan.

Ultrasounds are very useful for providers and can give parents an initial image of their growing child. An ultrasound is performed by a sonographer, usually within a health care institution or clinical facility. While there are many types of ultrasound scans that exist, the most common are abdominal ultrasounds and transvaginal ultrasounds. Transvaginal ultrasounds are typically performed during the earlier part of a pregnancy when the embryo is small and difficult to detect. An instrument is inserted into the vagina to capture clear embryonic and/or foetal images.

However, with abdominal ultrasounds, a woman generally lies on a table while the sonographer captures multiple 2D images of the growing foetus. A wand is used to bounce waves off of the bones of a developing foetus in order to capture these images. Women are advised to drink plenty of water before the procedure so that professionals can get clear pictures. Oftentimes, sonographers can also determine the sex of a baby and reveal it to parents, if they so wish. However, this is just a luxury because all doctors are really looking for is proper growth and development.

There are many things that an ultrasound scan can tell health care providers about a developing foetus. Sonographers are able to measure blood flow to a foetus's brain, heart, and other extremities, an approximate foetal weight, the length of the foetal extremities, the position of the placenta, and the approximate gestational age. Ultrasounds are safe during any stage of development in a pregnancy and the amount of radiation that is emitted from an ultrasound is minimal.

Recently there has been an increase in pregnant women who seek out 3D and 4D ultrasounds to get more detailed images of their developing baby. These ultrasounds are usually done by private agencies who offer these services for an additional cost. Women who get 3D/4D ultrasounds usually have the option to purchase a CD with a video of the procedure and can get additional photos which show the foetus's basic face structure more clearly than the original 2D version. Although these ultrasounds are nice to have, some doctors advise against their use because it can cause unnecessary worry about a foetus's development.

What Is 3D Ultrasound?

You area happy future mom and can't wait to see your baby. The only opportunity to do it now is ultrasound diagnostic. You could have standard 2D ultrasound that will show your baby in white and back colors or find new 3D/4D technologies useful for you. These technologies will help you to find out what your baby's smile looks like, as well as to see who the baby looks like.

With the 3D ultrasound technique you will be able to see three dimensional images of your fetus like in 3D movie. The technique was developed in 1987 by Olaf von Ramm and Stephen Smith at Duke University.

3D ultrasound was actually invented to prevent fetal anomaly on the early stages of pregnancy. But today there is also popular usage of 3D ultrasound that allows future moms to see their babies in real projection before they are born. 4D baby scans are almost the same as 3D scans except that 4D shows fetal movement like a video clip.

Advancements in 3D ultrasound technology now allows parents, family and friends to watch with incredible real-time clarity as the unborn baby moves in the mother's womb.

The 3D/4D ultrasound images are viewed on a large screen, and are accompanied by the sounds of the baby's beating heart. Parents-to-be receive keepsake 3D photos and a DVD capturing their baby's ultrasound forever.

The best time to do 3D ultrasounds is 24-32 weeks, and ideally between 26 and 30 weeks. Some centers advise parents to come in between 26 and 28 weeks to get the best images.

After 32 weeks getting 3D images of the fetus is nearly impossible, because the baby is bigger there is less room so it is more difficult to get a nice image.

Is 3D ultrasound harmful? - There has been no medical harms to the mother or fetus directly attributed to 2D or 3D ultrasounds over the course of 30-year history of its medical use.

The risks of 3D ultrasound is the same as for 2D, as it uses the same ultrasound waves at the same intensity. 3D ultrasound images are actually 2D ultrasound images taken at various angles to construct a real appearance of the baby. So the potential risk of 3D ultrasounds, if any, would depend on the duration and intensity of the ultrasound session.

The Impact Of Ultrasound Medical Equipments To The Medical Field

There are many different uses of ultrasound in the medical profession and it can benefit you as a patient, if used properly. It allows the medical professionals to see within the body and to discover if any abnormalities are present or if any problems exist that are going to need to be taken care of further. Here are some of the more common ways in which ultrasound is used and some of the more specific uses of ultrasound medical equipment that may be of benefit to you.

Ultrasound is commonly used during pregnancy in order to make sure that the fetus is developing normally. It can help the medical professionals to discover, not only the size of the fetus but any abnormalities that may be present which are going to cause problems for either the mother or the unborn child. It is not always necessary to have an ultrasound during the time that you are pregnant but if the doctor suspects that something may be amiss, it may become necessary. Many mothers and fathers alike look forward to the ultrasound and the fact that they are going to get a sneak preview of their child, even before it sees the light of day. Interestingly enough, it is also during these visits that the sex of the child is determined and it is up to the parents to decide if they want to know the sex of the child or not.

Some of the other uses of ultrasound can be beneficial for other parts of the body. This is especially the case when it is suspected that there may be some type of tumor or abnormal growth in the area. Additionally, various blockages can be determined through ultrasound technology and the medical equipment that is available. For example, blood flow throughout the body can be determined and any blockages can be viewed through ultrasound as well as problems in the gallbladder, leading to blockages and disease.

As far as some of the portable ultrasound equipment is concerned, these allow the physician to do noninvasive examinations inside of the body. Some of the more common types of medical equipment that can be used for this purpose include the transrectal ultrasound (prostate), the transvaginal ultrasound (vagina, uterus and ovaries) and the transesophageal echocardiogram (heart by way of the esophagus). If it weren't for these specific types of portable medical devices, much more invasive techniques would need to be used in order to determine if there were any problems.

Of course, even though ultrasound has been around since 1930 in the medical field, it is still an emerging technology. There are certain to be advances that are made in this technology which will allow physicians to get an even better view of the inside of your body, and that will benefit you greatly. If you have a need for such equipment, it would be a good idea for you to see what the newest technology is and then if necessary, to travel to where it is available. In some cases, it can make the difference between an accurate diagnosis and a professional guess.

Ultrasound Technician Salary - A Positive Future For Ultrasound Technicians

It's a common misconception that the only use of ultrasound or sonography is for taking images of a fetus inside a pregnant woman's uterus. Whilst this is the most well-known application of sonography, there are other ways that sonography is used. If you're thinking of pursuing a career in this field because of the job security and high ultrasound technician salary it provides, you may also feel delighted that you have the option of specializing in a particular field that is of interest to you.

Before anything else, you may feel the need to know how much an ultrasound technician salary is. Based on the Occupational Employment Statistics provided by the Bureau of Labor Statistics, diagnostic medical sonographers or ultrasound technicians receive an annual mean salary of $63,640. You can earn as much as $85,900 or more depending on a number of factors like work setting, years of experience, geographical location, and additional training and education, particularly cross-specialization that you undertook. Most ultrasound technicians work in hospitals where they earn $63,770 a year. Some work in physicians offices earning $63,820 annually. There are also those that are employed by medical and diagnostic services where they are being paid $61,820.

Ultrasound technicians with less than one year of experience usually receive from $30,304 to $51,395 in annual median salary. For a year to four years of experience, you should be up to $36,164 to $52,267 a year. Staying on this job for 5 to 9 years, you can expect an ultrasound technician salary of $41,724 to $59,793 a year. With this incentive of staying on the job from 10 years or more, you have the potential to earn as much as $75,000 or more a year.

If obstetrics and gynecologic sonography (where you'll be taking images of the female reproductive system) is not to your liking, you can specialize in other areas like abdominal sonography which is concerned with taking images of the liver, kidneys, gallbladder, spleen, and pancreas; or neurosonography, where images of the brain and other parts of the nervous system are taken. In addition, sonographers may specialize in breast sonography, vascular sonography or cardiac sonography.

From 2008 to 2018, it is estimated that 9,200 more ultrasound technicians will be needed to fill up the expected vacancies. This indicates a projected employment growth of 18% for the ultrasound industry. In part this is due to the increasing number of elderly people who require diagnostic imaging services. Ultrasound imaging is also fast becoming the preferred choice of diagnostic imaging because it is more economical and safer compared to other radiologic procedures. Finally, this ultrasound imaging technology is evolving rapidly and there are now new sonography procedures that let technicians scan and image areas of the body where ultrasound has not traditionally been used.

An ultrasound technician salary is a very stable source of income for anyone considering this career. In the coming years, there will be an even greater need for qualified sonographers. Even if the unemployment rate is hovering at double digits, ultrasound technicians and other healthcare occupations will be less affected, because the healthcare industry is the fastest growing industry in terms of new jobs being generated.

Liver Ultrasound Preparation

An ultrasound test is a radiology technique, that uses high- frequency sound waves to produce images of organs and structures of the body. The sound waves are sent through body tissues with a device called a transducer. The transducer is placed directly on top of the skin, that has a gel applied to the surface. The sound waves which are sent by the transducer and are transmitted electrically on to a viewing monitor. The echo images are then recorded on a plane film and can also be recorded on video tape. After the ultrasound, the gel is easily wiped off.

Live Ultrasound Technical Term

The technical term for ultrasound testing and recording is "sonography". Ultrasound testing is painless and harmless. Ultrasound test involve no radiation and studies have not revealed any adverse effects.

Liver Ultrasound Purposes

Ultrasound examinations can be used in various areas of the body for a variety of purposes. These purposes include examination of the chest, abdomen, blood vessels (such as to detect blood clots in leg veins) and the evaluation of pregnancy. In the chest, ultrasound can be used to obtain detailed images of the size and function of the heart. Ultrasound can detect abnormalities of the heart valves, such as mistral valves prolapse, aortic steno sis, and infection (endocarditis). ultrasound id commonly used to guide fluid withdrawal (aspiration) from the chest, lungs or around the heart. Ultrasound is also commonly used to examine internal structures of the kidneys, the ureters, liver, spleen, pancreas, and aorta within the abdomen can be examined. Ultrasound can detect fluid, cysts, tumors or abscess in abdomen or liver.

Impaired blood flow clots or arteriosclerosis in the legs can be detected by ultrasound. Aneurysms of the aorta can also be seen. Ultrasound is also commonly used to evaluate the structure of the thyroid gland in the neck.

An abdominal or liver ultrasound plays a crucial role on diagnosing many liver diseases, including a fatty liver. To get accurate result, its very important to understand and know how you should prepare for a liver ultrasound.

Liver Ultrasound Preparation Guidelines

Do not drink or eat 6 hours before the test.
ON the day before the test do not eat - fresh fruits and vegetables, fired and oily food, milk, eggs, bread.
What you should eat - cooked vegetables, puree,marmalade, honey, roasted bread, soup, and rice
No medications are needed to be taken before Ultrasound

Liver Ultrasound scan is completely painless

Here is estimated procedure:

Lying on to an ultrasound table
A special gel will be spread upon your abdomen
The tester will move a tool called "transducer" (looks like a small wand) over the gel, that will create and capture the most relevant images.
The tester will process and look at the images, and will enter his conclusion
Total estimated time of the test: 2- 30 minutes

There are two types of people, one who are born rich and others who become rich & i am the second one.

Are 3D/4D Ultrasounds Safe During Pregnancy?

Many of the parents crave to know about the unborn baby in the mother's womb during pregnancy. Pregnancy ultrasound scan that is 4D ultrasound and 3D ultrasound allows the impatient parents to have a glance into the womb. Pregnancy ultrasound comes from a machine which creates an image of the interior part of the body.

Ultrasound during pregnancy reveals many details about the baby:

• Health of the heart of the baby

• Size of the baby

• The condition of the other organs of the baby like the brain, kidney, spine and how they are growing

• Anticipated date of birth

• The pictures move on the computer screen and it almost looks like a movie.

In the excitement of trying to see the baby we also need to know how safe are the 3D/4 D ultrasounds?

4D scan is equally safe as compared to the 2D scan. Ultrasound scans, do not carry any form of radiation.

The only risk is the raised temperature. It is known scientific fact that the sound waves cause rise in temperature among the tissues they pass through. This rise in temperature depends on the acoustic power and the duration of the scan. There is enough solid evidence that the elevation of temperature by 1.5 degrees Celsius is safe and within the accepted standards. In reality this temperature is rarely reached.

For causing potential harm it is necessary that the temperature rises to 41 degrees Celsius but this temperature is never reached during pregnancy ultrasound scanning. Acoustic outputs that get produced by the B MODE ultrasound are not as high enough to produce harmful effects.

The society of obstetricians and Gynecologists of Canada and Health Canada has produced some guidelines for the diagnostic ultrasound. They list that ultrasound should not be used for the below reasons:

• To determine the sex of the baby, solely for non medical purpose

• For commercial use, like trade shows or capturing videos of the baby

• To capture the picture of the baby, solely for non medical purpose

Benefits of ultrasound during pregnancy:

• It provides the care provider and the mother with vital medical information. It helps to decide the future course of action.

Potential risks of Pregnancy ultrasound:

• There is no solid evidence to indicate that the levels of ultrasound used on humans are harmful. But, some animal studies indicate with higher levels of ultrasound some changes in cell structure or function may occur. It might even lead to cell death. These studies show that the tissue or body parts under examination under the high frequency waves get altered.

• The biggest risk is the possibility of identifying something outside the normal range, with the baby. These unusual findings generally get resolved on their own or they are simply normal.

It is a path breaking experience for the mother to have an ultrasound and is safe too.

Ultrasound Machines - What's This For?

Most medical conditions and diseases are much less likely to be fatal than in decades past, thanks to advances in medial science. Medical diagnostics allow most disorders to be caught earlier, thus allowing treatment to begin more quickly and accurately. The popularity of ultrasound machines, which use high frequency sound waves to detect problems in patients' internal organs, has made rapid accurate diagnosis much easier.

Ultrasound machines have been especially helpful in diagnosing cardiac diseases. We know the criticality of heart in a healthy human body. In their initial stage, heart diseases can be cured through medicine and surgery. However, without a proper diagnostic tool, it was very difficult to ascertain a heart ailment earlier. Medical imaging of heart has drastically reduced the number of patients dying due to heart ailments.

Let us take a look at some of the workings of ultrasound machines. All machines have what is known as a transducer probe, which both emits and receives the ultrasound waves. Pulse controls are used to control the different wave properties of frequency, duration, and amplitude. Other components of the machines include a CPU, a mouse, a display, and a printer.

Ultrasound works by sending ultrasonic waves into the part of the body being examined. When interrupted by abnormal tissue such as tumors or the boundaries between tissues, the ultrasonic waves are reflected or echoed. The ultrasound machine calculates the distances traveled by those reflected waves to generate 2D images that display the distances and intensities of those echoes.

Internal organs can be sound through the aid of an ultrasound machine. A radiologist can use the machine's controls to view a specific section of any organ. Ultrasound scans are perfectly safe and have no side effects. Medical personnel can even use mobile machines in an emergency.

However, ultrasound imaging is still a medical procedure, and as such, should only be administered by a medical professional trained in radiology. A novice would not be able to properly interpret the results. Also, long term exposure to ultrasound waves has negative physical side effects, and an expert is necessary to regulate the equipment to avoid long term problems.

Ultrasound machines have given medical imaging diagnostics quite a boost since they have gained popularity. The ultrasound uses high frequency sound waves to make visuals of internal organs and tissues. Since cardiac health is a top priority in maintaining overall health, the use of ultrasound has given doctors the jump on once-fatal conditions. Before ultrasound, it was virtually impossible to catch heart ailments before they progressed into more advanced, less curable stages. Since the advent of ultrasound, the number of patients who die of heart problems has decreased substantially. Ultrasound imaging is a medical procedure and therefore only a doctor trained in radiology should perform it.

Ultrasound Technician Career Guide

Ultrasound technician, more commonly referred to as the diagnostic medical sonographer is responsible in making patient's diagnosis with the use of sound waves from a special ultrasound machine. This profession is becoming in demand in hospitals, clinics and diagnostics laboratories because in 2008 alone, the employment in this field reached 50,800 jobs. Let us review the different aspects of a career in diagnostic medical sonography.

Ultrasound Technician Job Description

Among the responsibilities of sonographer is to work with a physician in the diagnosis of the patient's disease. He provides the best and the clearest image taken from either the internal organs or tissues for the final diagnosis and interpretation with the physician. Reading, calculating values and rendering initial/preliminary diagnosis of the patient's disease are also the duties of ultrasound technician. Keeping records of patients, maintaining the ultrasound equipment, managing ultrasound imaging department and working overtime are also included in the job description of diagnostic medical sonographers.

Training Requirements

Want to pursue a career as sonographer? Ideally, the first requirement is a background in algebra, natural sciences and basic physics. The usual time to accomplish a complete training is two years. There is also a four-year degree course which will offer more stability when it comes to employment after school. Typical coursework is composed of patient care, anatomy, medical ethics, physiology and medical ethics.

Among the specialized fields of sonography includes obstetric and gynecologic, abdominal, neurosonography, breast, vascular or cardiac sonography. Obstetric and gynaecologic sonography is about scanning and examining the female reproductive organ while abdominal sonography is concerned with the pancreas, spleen, gallbladder, liver, and kidneys. Nuerosonography is all about brain examination, breast sonography deals with the tissues inside the breast and cardiac sonography deals with the heart.

Complete training to become ultrasound technician can be obtained in several accredited school and universities. There are also trainings provided in vocational technical training institutes. In 2003, the Commission on Accreditation for Allied health Education Programs passed 100 programs for accreditation in the field of ultrasound sonography.

After completing the training to become a sonographer, there are options of whether to take exams to be licensed, although it is not required for some states to be a licensed. According to the US Bureau of Labor and Statistics, sonographers can have higher salaries if licensed. The American Registry for Diagnostic Medical Sonography (ARDMS) will issue professional license following the completion of the full training in accredited schools.

Before applying as sonographer in a certain hospital, make sure to know the state rules regarding the state requirement of professional license by sonographers. According to the Society of Diagnostic Medical Sonography, New Mexico and Oregon are requiring licensed from ARDMS but some states won't require state license or professional license to be accepted as sonographer.

Salary and Benefits

Although, yearly income differs from private laboratories and government hospitals, the annual income of ultrasound technicians in 2002 is $50,390 (doctor's clinic) and $47,530 (hospitals).

The demand for sonographers in the future will be increased by hospitals and also there will be an increased employment rate for doctor's clinic and diagnostic laboratories because of the advancement in technology which will bring more affordable mobile devices. Moreover, medical insurances will expand coverage in different sonography examinations. According to the US Bureau of Labor and Statistics, the employment for sonographers will increase from average to be faster in 2012.

Getting a career in ultrasound technology is a wise decision since it only requires a short period of time for studying unlike other medical courses which requires student to spend at least four years in college. Decide on the accredited university now and enroll in the programs to achieve a training and expertise as ultrasound technician.

What is the Value of Ultrasound Gel During a Medical Ultrasound Examination?

Medical Ultrasound relies on the reflection, refraction and scattering of ultrasound waves by the body structures to produce an image. If it did not occur, none of the Ultrasound energy would return to the ultrasound transducer to be converted in to an image. The strength of reflection of the Ultrasound wave at an interface is partially dependent upon the difference in acoustic impedance of the two structures making up the interface. The greater this difference in impedance, the more of the ultrasound wave is reflected.

At the skin / transducer interface there is a very significant difference in the acoustic impedance of the two structures and therefore virtually all of the Ultrasound energy is reflected. Couple this fact with the observation that the Ultrasound has to pass through this interface twice, once on the way into the body, and once on the way back out to the transducer, and you can easily see that no significant ultrasound energy is going to return to generate an image.

Furthermore, Ultrasound passes through soft tissue at an average speed of 1540 meters per second. In air it is approximately 331meters per second. An Ultrasound machine is unable to correct for this difference, so any air between transducer and body would cause additional issues. This situation is easily alleviated by the use of Ultrasound gel between the transducer probe and the body. This effectively removes the air/skin interface and provides a transition between the transducer and skin which extensively reduces the reflection of the sound waves. Its success in doing so is very easily demonstrated by simply trying to scan with a dry transducer probe on dry skin.

So, what makes a good gel?

A good Ultrasound gel may be blue tinted or clear, but will be non-staining. It will be acoustically correct for the broad range of frequencies used in Diagnostic and Therapeutic ultrasound procedures and in Aqueous suspension. It is also important that it is Hypoallergenic, bacteriostatic, non-sensitizing and non-irritating. There are many medical ultrasound gels on the market and there is very little difference in their constitution except some are runnier than others.

Sonographers vary in whether they prefer a runny variety easily manipulated around the body during the scan, but also tending to spread outside the field of interest and wetting patients clothes; or the less runny variety, which can dry off during an extended scan (requiring additional gel to be applied) but is more easily controlled. A further difference in gel is the choice of clear or blue tinted varieties. The latter does not stain clothes but can make it easier to see where the gel is after the examination, allowing the patient to dry it off more thoroughly.

Do You Have To Take Core Classes Before Entering Ultrasound Technician Programs?

Ultrasound technician programs require trainings in order to complete the entire coursework to become certified in the field of ultrasound sonography. Do you have to take core classes before enrolling in an accredited university to become ultrasound sonographer? Yes. And here are some reasons why it is critical to have undergone several related ultrasound technician programs before pursuing to become a successful ultrasound technician.

One of the job requirements of being an ultrasound sonographer is to generate and capture clear images of the needed organs or veins of the patient's body. This is necessarily by using the ultrasound machine's sound waves to get images. Furthermore, patient care is needed by the technician because he is the one responsible in securing a position for the patient in order to get the images he needs for initial diagnosis.

With this job description, it is therefore needed to have some background in biology terminology, and physics to be able to enroll in an ultrasound technician programs. Furthermore, several of the schools are requiring the applicants to have an associate degree program diploma in order to continue pursuing a career in ultrasound technology. The one year degree program for ultrasound sonography can only be vital for professional who are already inclined the field of allied health. This is only to improve, expand and acquire more knowledge in ultrasound technology.

Aside from basic high school subjects such as anatomy, physics, biology and an optional associate degree course, there are still core courses which an ultrasound technician needs in order to become effective and efficient in his work. Here are some of the important credits which should be earned by the technician in order to be qualified in ultrasound technician programs.

Anatomy, a branch of biology is the study of the different structures of the human body as well as the internal and external organs. This is needed for the ultrasound technician so that the location of each body organ is analyzed and studied to make use when organs and body parts are being studied by the ultrasound machine.

To know the functions of the several body organs and body parts, it is essential to study physiology. This is also important and vital for the work of the technician because this is a continuation of the anatomy subject.

Medical terminology is the study of the different jargons and languages used by medical professionals. Medical etymology, an equally needed subject should also be studied by the technician.

Ultrasound principles are important for the technician to know the fundamentals of ultrasound sonography including the different characteristics of the machines such as echoes and Doppler ultrasound.

Physics is another important coursework to be finished in the degree of ultrasound technology. This is because the study of matter, forces and motion are also important for the ultrasound machine utilization.

Proper care and maintenance of the ultrasound machines are essential to keep the machines working properly and efficiently. This is why a coursework entitled equipment use and maintenance is included in the curriculum of the ultrasound technician programs.

Patient care is also an important coursework for the technicians to know the proper care and management of the patients especially for those who are already very sick. Proper positioning of the patient is not an easy job for the technician that is why proper way to do the positioning must be taught in school for the technician to do it properly in the laboratory room.

Having a background on the several core classes is essential for the ultrasound technician programs not only for proper accomplishment of the task of getting clear images from the patient's damaged body organ but also for proper care of the patients and for proper administration and maneuvering of the ultrasound machine.

Ultrasound Tech Schools - Opportunities For Ultrasound Technicians

Ultrasound tech schools are an outstanding chance for all the students that desire to enter a medical ultrasound tech course. They could as well study management strategies. If you 're attracted in pursuing a career as an ultrasound technician, initially you have to get an associate 's or bachelor 's health-care diploma from one of the ultrasound technician schools, granting you admission to a clinical ultrasound program.

There are various types of ultrasound technician specialties to choose from, depending on your personal area of interest in this medical technology domain, and you can pursue your preparation at any of the ultrasound technician schools, either a vocational one, offering certificates and 2-year Associate degrees (as an example Associate in Specialized Technology Degree), or four-year faculties and universities, leading to a Bachelor of Arts degree.

Depending on the school, admission necessities can vary, some programs may need interviews, entrance assessments and prior allied health experience and recommendation, but all ultrasound tech schools necessitate a high-school diploma or a GED equivalency. Note that all ultrasound tech schools must be certified by the Commission of Accreditation of Allied Health Education Programs (CAAHEP), but students who attend non-AAHEP-certified ultrasound tech schools have the possibility of taking the ARDMS certifying exam after completing a year of work experience.

Usually the curriculum for ultrasound tech schools must cover, in addition to the coursework, hands-on instruction in sonographic physics and instrumentation, gray scale and color-flow Doppler sonography, medical ethics and terminology, human anatomy and physiology, basic obstetric and gynecologic sonography. Ultrasound tech schools may also necessitate the possibility of taking an internship in an ultrasound facility. There you 'll be able to study from professionals in this area of activity.

A remarkable figure of certificate and two-year Associate degree applications offered by ultrasound technician schools grant the education for entry-level professions in this domain, but if you are eager to obtain a senior job, you can opt for sections like diagnostic medical sonography (obstetric and gynecologic sonography, diagnostic cardiac sonography, abdominal sonography, vascular technology for bloodflow and hemodynamics, neurosonology for brain and spinal cord). Ophtalmology or ophtalmic biometry involve a four-year Bachelor 's certification.

There are different choices for completing an ultrasound technician program in one of the ultrasound tech schools, a number of students are willing to obtain extra qualifications like registration with the ARDMS (American Registry of Diagnosic Medical Sonographers); meanwhile, another part of students choose achieving extra qualifications provided by trade organizations.

Ultrasound technicians specialize in sound wave method so they can get images of patients' internal tissue and organs. Then the ultrasound technician must assist the physician in decoding the imaging in order to provide the patient an accurate diagnosis. The ultrasound technician profession also deals with a direct interaction with the sufferers, manage their information, add it in the patient history, cope with the facilities and the apparatus.

Graduation from one of the ultrasound tech schools leads to the registration through ARDMS (American Registry of Diagnostic Medical Sonographers) and this offers you more recognition when dealing with potential employers at hospitals or clinics. More frequently then not, the ARDMS credential is seen as a condition of employment for ultrasound technicians.

Ultrasound Technician Career Guide

Ultrasound technicians, diagnostic medical sonographers or ultra-sonographers are responsible for operating sonography equipment in hospitals, clinics and health care centers. This equipment helps make patient diagnoses by examining their internal organs with the latest ultrasound technology. The ultrasound technician views blood circulation, organs and tissue to make the diagnoses. A common example is the periodic ultrasound scan prescribed for pregnant women where the technology helps keep track of the fetus's health in the womb. They play an important role in the health care process since it is a non-invasive diagnostic method.

Ultrasound Technologists' Job Description

What Does An Ultrasound Technologist's Job Involve? An Ultrasound Technician Does The Following:

* Interacts with patients to note their medical history

* Explains the procedure involved for the ultrasound test

* Helps the patient prepare for the test

* Adjusts and programs the scanner

* Operates the scanning equipment

Ultrasound techs also use equipment such as oscilloscopes, cameras and video recording devices to collect images for creating permanent records of diagnoses and investigations. They also study the images to create reports about the patient's condition. If there is something unusual or abnormal, they might decide to investigate further. The medical report is prepared after the scan by the ultrasound tech along with their expert comments. The ultrasound tech is a skilled professional who assists in biopsy procedures and surgeries. Ultrasound techs can also get called out to multiple locations for their expertise.

Ultrasound Tech Career Options

They have various career options. Thanks to the changing technology in the medical field and a growing population, the demand for trained ultrasound technologists is very high. The ultrasound technology is also becoming very popular as a preferred procedure because it is safe and non-invasive unlike conventional invasive procedures such as surgery that can be costly, painful and time-intensive. The need for ultrasound technicians is therefore always growing as more and more people opt for sonography.

Pay Scale For Ultrasound Tech Jobs

Ultrasound technologist salaries range according to experience, expertise and where they work. The average hourly wage earned by ultrasound technologists in 2011 is $18 to $25 per hour according to the US Bureau of Labor and Statistics.

Ultrasound technicians are among the highest paid in the medical industry. The exact salary depends on their experience, their employer, the city in which they work and the certifications they hold.

Most ultrasound techs will work with doctors' clinics, hospitals, diagnostic imaging labs, private hospitals and healthcare centers, etc. Imaging equipment could also be used outside of these places in locations such as birthing centers and physician's offices where they would need an ultrasound technician to operate it.

Since ultrasound technicians jobs involve work-related health issues such as musculoskeletal disorders, their work environment is monitored by OSHA, the US Department of Labor's Occupational Safety and Health Administration and the SDMS, the Society of Diagnostic Medical Sonography to ensure their safety.

If you're ready for a booming career in the medical industry, you'll want to consider working as an ultrasound technician. Learn about the ultrasound technician requirements from http://www.ultrasoundtechniciansalarydata.com.

Becoming an Ultrasound Technician Learn the Facts

Ultrasound technicians, or diagnostic sonographers, use high frequency sound waves to generate an image for medical diagnostic purposes. Ultrasound technology does not carry the risks of other diagnostic methods such as radiation. Because of this, the use of ultrasound is growing.

The demand for ultrasound technicians is increasing. According to the Bureau of Labor Statistics, employment is expected to increase 19 percent by 2016.The average salary of an ultrasound techs in the United States is approximately $50,000 a year. However, this can vary based on certification, experience and location.

There is no standard level of education required to become an ultrasound tech. The most common duration of an ultrasound training program is two years, but four year programs and one year certificate programs are also available.

Most employers prefer to hire techs who have trained at an accredited educational institution

There are over 150 accredited programs to train ultrasound techs in the United States. Many of these programs even allow students to become an ultrasound tech online. Ultrasound tech online classes provide flexibility and convenience in the educational process.

Once they complete their education, students can apply for certification through the Association of Registered Diagnostic Medical Sonographers or the American Registry for Diagnostic Medical Sonography.

How to Find Ultrasound Technician Accredited School:

Those who like working with people and are considering a career in the medical field might find an ultrasound career very fulfilling. In order to join the ranks of the highly trained Ultrasound Technician one must first attend a fully accredited school to qualify for jobs in the field. Here is how to find Ultrasound Accredited Schools.

Ultrasound techs are the professionals called on to use a transducer instrument to view the organs located in the human body.

The transducer radiates and senses the sounds produced. Computer generated images are then produced by the sound waves. It takes a fair amount of training at an accredited school to practice this profession. Potential students can find fully accredited ultrasound tech online schools simply by performing a search on the Internet.

There are online schools that offer students a certificate for several months of study while others offer an associate or bachelor's degree in this very rewarding career. First it is important to decide on which course of study to pursue.

This should narrow the field down. Next, prepare a list of several schools found online. Check information on the site to make sure that they are accredited by the Commission on Accreditation of Allied Health Education Programs (CAAHEP). Contact Schools at that point for more information.

Using Ultrasound Therapy Machines to Reduce Joint and Muscle Pain

Ultrasound therapy machines are used by trainers, chiropractors, and therapists for treating joint pain, arthritis pain, and muscle pain. Many people believe that this type of therapy alleviates their pain and also helps in their healing process.

In the ultrasound therapy, very high frequency sound waves generated by the ultrasound machines are allowed to deeply penetrate the skin of your painful or injured area. In this procedure, a probe or wand with a rounded head, which is further attached to a home ultrasound machine, is used by holding it in hand. A gel is rubbed on the skin and the probe head is then gently moved on the affected body area by making small circular motions.

The ultrasonic (high frequency) waves are generated by the vibration on the head of the hand held probe. These waves then travel all through the skin causing tissue vibration in the affected areas of the body. This vibration of tissues heats them up, resulting in many beneficial effects on the injury. This is so because now the heated area draws more blood as a result of which large amounts of nutrients are delivered to the affected area. The main aim here is to somehow increase the flow of blood so that large amounts of nutrients reach the affected cell tissues.

The dosage of therapeutic ultrasound can easily be varied by slightly altering the frequency of the ultrasound beam. All the necessary controls for achieving this are placed on the control panel of ultrasound machine. A much deeper penetration of waves is achieved when the frequency is lowered, successfully dealing with any deep tissue injury.

High frequency dosages are normally used for all those injuries which are much closer to surface of the skin. A normal therapy session lasts about 4 - 12 minutes depending upon the injury.

There are some areas which should be avoided during the usage of ultrasound therapy machines. You should never use ultrasound therapy machines near the brain, spine, face, lungs, liver, kidneys, testicles, or ovaries. Care should also be taken when ultrasound therapy machines are used on pregnant women or people taking coagulant medicines.

Ultrasound therapy is usually safe when it is administered by some trained person or therapeutic professional. This is due to the ability of the handheld probe to burn the surface tissues or even cartilage and bones if continuously, kept in place, on some area for a long duration.

Ultrasound therapy machines are now also available for fibromyalgia treatment and rehabilitation. As fibromyalgia involves a soft tissue inflammation, therefore a particular type of portable ultrasound machine is used in its treatment. It is essential to purchase quality ultrasound therapy machines, which are approved by FDA. They should also be covered with a minimum one year warranty.

Today you can also purchase ultrasound therapy machines for personal use at home. These models would cost you few hundred dollars. You should however consult your doctor before using such ultrasound therapy machines.

What Are The Risks Involved With Ultrasound Scans?

Although ultrasound was first discovered in the 1800s, medical ultrasound was not introduced as a practical application until the 1950s. Today, ultrasound scans are most frequently used in the obstetric setting but are practical in many other medical areas as well. The safety and ease of use has made these machines a lasting diagnostic tool in the medical community.

History of the Medical Ultrasound

Two men are touted as being the founding fathers for traditional medical ultrasonography. Austrian Dr. Karl Theodore Dussik first used ultrasound to diagnose a brain tumour. Dr. Karl then published his findings, the first published article about medical ultrasound, in 1942. Some 15 years later, Professor Ian Donald developed the ultrasound machine, which used current technology for the time. This machine was first tested in 1957 and then used on the first pregnant woman in 1958.

How does it work?

An ultrasound scan produces pictures by using sound waves. These waves bounce off of the tissues in the body and back up to the transducer in order to produce the black-and-white picture on a computer screen.

Who can perform an Ultrasound?

Only those who are licensed as ultrasound technicians can perform one of these scans. Physicians are also permitted to perform an ultrasound as they received all of the necessary training during schooling.

Where on the body can Ultrasound be used?

Ultrasounds are most often used in obstetric applications to diagnose gestational age, estimate foetal weight and health, determine placental placement in the uterus and assist with diagnostic testing such as amniocentesis. The medical ultrasound has many other applications as well. It can be used to view anomalies in the abdomen, urinary tract, thyroid, breasts, heart and circulatory system.

How safe is an Ultrasound?

Ultrasound is used in a variety of medical applications because it is non-invasive and offers basically no risk to the patient. Ultrasound does create a bit of heat during the actual test. This heat is general only about one degree centigrade and is dissipated by the body rather easily.

Many studies have been conducted to examine the effects of ultrasound on a foetus after birth. One such study was conducted by the University of Western Australia. In this study, foetuses were exposed to as many as five different ultrasound tests throughout the gestational period. The end result of the study is that there was no developmental or physical effect on a child.

Other Considerations

Ultrasound scans are a tool used for diagnostic purposes in the medical community. For this reason, patients should never be afraid to ask questions. If something has not been explained to the satisfaction of the patient and/or family, request a different explanation or more information from another healthcare practitioner.

Since ultrasound was first used in the medical community it has been one of the most widely used pieces of diagnostic equipment still to this day. Ultrasound is very versatile and non-invasive which makes it highly popular amongst healthcare practitioners. There is virtually no risk to the patient who receives an ultrasound and no adverse effects on a foetus.

For further information on pregnancy, well being and ultrasound scans, visit Ultrasound Direct who provide pregnancy scans across a number of clinics throughout the UK.

Revolutionary Home Ultrasound Machine Treatment

The home ultrasound machine is an innovative home remedy, from which treatment was once available only to hospitalized patients. This revolutionary home ultrasound machine works the same at home, as it does in the hospitals for therapeutic use. Significantly priced below the hospital ultrasound machines, these home ultrasound machines do not require the overhead cost incurred from hospitalization.

The pain-relieving ultrasound devices work by pulsating ultrasound waves at differing wave lengths that flows out of a hand held wand. Apply the water-soluble gel to the afflicted skin area and use the wand to target the painful soft tissue. There are different power settings on the hand-held wand: low, medium, and high. There is a 30-minute automatic off switch that prevents tissue damage.

Therapeutic ultrasound machines help to alleviate pain, decrease inflammation, and allow for good blood flow to the area for faster healing. The common ailments that the home ultrasound machine treats include neuralgia, arthritis, sports injury, carpal tunnel syndrome, strains and sprains, tennis elbow, golfer's elbow, tendonitis, upper and lower back pain, sciatica, plantar fasciitis, heel spurs, fibromyalgia, and tension headaches.

These therapeutic ultrasound devices do not emit any harmful x-rays, or any other harmful rays, that may be carcinogenic or detrimental to your body tissues. Ultrasound therapy devices do not hurt with treatment or cause bodily discomfort when applied correctly. The documentation that comes with the home ultrasound machine specifies its usage. A general rule of thumb is that you can treat each body area 1 - 3 times per day for up to 15 minutes each treatment. This can be accomplished daily or every other day. The large body parts like the thighs and legs can use the high power setting, and the smaller body parts like the elbows, knees, and hands should use the low to medium settings.

A good ultrasound therapy unit comes with a 1 MHz wand, gel, documentation, and 110/240 V universal plug in a convenient traveling case. This allows for the portability of the home ultrasound device. You can take it traveling when you know you are going to have some new aches and pains from the different hotel beds. You can continue your home ultrasound therapy on the road without interruption or having to reschedule with a physical therapists; or wait to return home. Overall an ultrasound therapy unit is a worthwhile purchase for those with chronic discomfort that require ultrasound treatments or treatments for an acute injury like a pulled back muscle or sprained ankle.

Which Ultrasound Technician Schools Are The Best Options?

Pursuing a career to become an ultrasound technician can only be accomplished when choosing which ultrasound technician schools is the best. Though many schools, community colleges and universities offer training programs in ultrasound sonography, it is still essential to make necessary precautions in choosing which ultrasound technician schools provide the best education to become successful in the career as ultrasound sonographers. Just one tip in looking for the best school, make sure that the university is included in the list of accredited schools certified by Commission on Accreditation of Allied Health Programs. Here are some of the reputable schools in ultrasound sonography.

The George Washington University Medical Center in Washington, DC, is among the ultrasound technician schools that provide certificates and bachelor degree diploma for ultrasound sonography. For the bachelor and degree holders who want to pursue specialization in ultrasound sonography, the university is offering the Sonography Certificate Program. For students, the Sonography Bachelors Program must be chosen because this is the program to be taken in preparation for the achievement of credential examination from the ARDMS. This is credentialing examination from the ARDMS is achieved after a year of graduation which will be the tool for the graduates to become in demand in the professional field.

The University Of Missouri School Of Health Professions is the only institution in the US to provide education for the Master in Health Science (MHS) in Diagnostic Medical Ultrasound (DMU). It also offers Bachelor of Health Science. The specific requirement for those who want to enroll in Diagnostic Medical Ultrasound is that he should be physically fit to maintain extended arm positions and lengthened pressure applications during procedures requiring ultrasound machines. Audible and visual Doppler technology both require an accurate vision and hearing standards to properly diagnose what is wrong with the patient.

The Florida's St. Vincent's Schools of Medical Science is accredited to offer one to two years of training certificate programs for ultrasound technicians who are already in the field of health care or for those who are certified as radiologic technologist. Other requirements to enroll in this university are coursework completion in anatomy, medical terminology, algebra, physiology and physics. Available specializations are vascular sonography, physics and instrumentation, obstetric, gynecological, vascular physics.

At Hillsborough Community College, there is a chance for the financially incapable students who want to finish a program in one of the accredited ultrasound technician schools. There are programs offered which were financed by the federal and state financial aid programs. The school offers classes for mathematics, physics and anatomy and can specialize in the field of gynecological sonography, abdominal ultrasound, psychology and obstetrics. There is a mini internship program provided by the school but the students can opt whether to participate in the on-the-job training provided.

The Central Florida Institute has campuses in Tampa Bay area and Orlando. It is a non-profit organization offering associate degree which can be accomplished in two years or less than two weeks. Some of the curriculums included in the associate degree program are neurosonography, obstetric ultrasound techniques, gynecological, and abdominal techniques. The only requirement for students who want to enroll is to have a drug test before anything else. After the drug test, the institute will guide applicants through their preparation for interview, resume writing and career management.

For reputable online ultrasound technician schools, there are those that offer online clinical degree programs. Some of the schools offering online degree programs are the Kaplan University, South University and the Rasmussen College. These schools are offering degree courses in the field of medical science in preparation for them to get certifications and examinations for the field of ultrasound sonography.

Several other reputable schools can offer bachelor degrees, associate degrees and programs which can only be accomplished in one year or less than. You just need to choose your bet among all the ultrasound technician schools and do the research for accreditation and for other important considerations the university must have in order for you to achieve adequate education, training and expertise to become successful ultrasound technician.

Doppler Ultrasound - The Doppler Effect in Ultrasonography

Doppler is commonly used in Ultrasound to diagnose discrepancies in the hemodynamics of blood flow. The Doppler Effect is applied in sonography to provide medical imaging of vessels and the flow within them. Both color Doppler and Power Doppler are used to image blood flow. Pulsed wave and continuous wave Doppler help diagnose patients where the speed of blood flow has to be measured. Doppler ultrasonography is useful in most applications that diagnostic Ultrasound is used in. Examples where Doppler is used are cardiology, obstetrics, abdominal, small parts and neurology. When imaging body parts a high frequency wave is sent into the body. If a moving target is encountered the original frequency is shifted by the wave that is produced by the moving target. The difference between the original frequency and the moving target is demodulated and manipulated to show either an image or a graph.

What is Doppler?

Austrian physicist Christian Doppler in 1842 proposed that the Doppler effect is seen in the change in colored light from stars, and the change in sound of a passing object as in a passing train. In 1845, he and Buys Ballot proved the Doppler Effect of sound waves: A sound's pitch would change if its source or recipient is in motion.

When sound is emitted as a constant by an object and a recipient is moving towards or away from the source a change in frequency will occur, this is the Doppler effect. As you can imagine this Doppler effect can give useful information when applied to the human body during Doppler ultrasound examination.

The received frequency is higher (compared to the emitted frequency) during the approach, it is identical at the instant of passing by, and it is lower during the recession.

Doppler Ultrasound

While B-mode ultrasound can show images from within the body, the movement of blood and its speed cannot be measured with it alone.

Doppler ultrasound can detect and measure the movement of red blood cells as they cause a change in pitch of the reflected sound waves (called the Doppler effect). There would be no phase shift (rate of change in pitch) if the blood wasn't moving.

How Doppler Ultrasound is Performed

Ultrasound technicians trained in ultrasound imaging (sonographers) place a probe (transducer) over the area of the body being diagnosed. First an image of the region of interest is acquired. Then the vessel is located and the transducer is angled so that the best Doppler shift can be obtained. The best location would be to be able to look directly into the vessel (much like looking into a tunnel). Because of how the vessels are located in the body this is of course often not possible. Thus maneuvering the probe or steering the ultrasound/Doppler beam will make this plausible.

Acquired Doppler information can be heard, shown on a chart (much like and EKG) or in colored blood streaming through the vessel.

Types of Doppler Ultrasound

Commonly, two types of Doppler transducers are used Continuous Wave Doppler and Pulsed Wave Doppler.

Continuous Wave Doppler ultrasound transducers use two crystals, one to send and one to receive echoes. The transmitter emits a continuous sinusoidal wave so a receiver can detect the phase shift. An audible sound is recorded and analyzed. CW Doppler provides high sensitivity to low velocities and detection of high velocities without aliasing. However, CW Doppler cannot distinguish between the sending and receiving signals or extraneous echoes. CW Doppler ultrasound does not produce images like Pulsed Wave Doppler does.

Pulsed-Wave Doppler Ultrasound is combined B-mode to produce images of a certain structure. PW uses a pulsed echo system, the PW transducer both sends and receives the signal. It sends in short bursts, on and off, so it can receive when it is not sending.

Why Doppler Ultrasound?

Ultrasonography is a less invasive and less expensive modality which is easy to schedule and perform in an emergency situation. Sonographers can be called to perform this as an alternative to arteriography and venography, which involves injecting dye into the blood vessels so that they can be detected as X-ray images.

Duplex Ultrasound

A duplex ultrasound is a combination of tests to see how blood moves through your arteries and veins. Duplex means that two types of ultrasonography are employed: regular B-mode ultrasounds, and Doppler ultrasounds. The conventional ultrasound shows the structures of your blood vessels and Doppler shows the movement of your red blood cells through the vessels and the sound of the frequency shifts.

Duplex ultrasound produces images that can be color coded to show physicians where the blood vessel is narrow or blocked. In some situation blood flow is reversed and an abnormal color pattern is created. With Color Doppler speed and direction of blood flow information is obtained.

Doppler Ultrasound Semantics

It is interesting to note that in sonography, the word Doppler is used similar to the way the word Kleenex is. People use tissues and refer to them as Kleenex when they're not. In sonography, the word Doppler is used when true scientific Doppler is not what is really being done. It's similar, but different.

The technical point I would like to make is that Doppler is technically concerned with sound frequency, whereas in ultrasound applications we compare the PHASE of the sound. In what we do, Phase Shifts are more detectable and are what we measure, not frequency, but it's similar so it's referred to as Doppler sonography. Semantics!

Rather than using true Doppler ultra sound, which would measure change in sound frequency, what we call Doppler actually compares the phase of the sound energy, and measures the shift in that phase. Phase shifts are more drastic than frequency shifts, so phase-shift-compared ultrasound, still commonly called Doppler ultrasound, magnifies the likelihood of detecting motion.

Other Uses of the Doppler Effect

In 1848, Hippolyte Fizeau proved the same effect on electromagnetic waves (Doppler-Fizeau Effect).

Today, common uses of Doppler are: radar detection of weather (to calculate distance and show direction of movement of weather pattern) to diagnose or forecast them, and police use doppler radar to detect speeding motorists.

Smartsound Ultrasound is an exclusive dealer for the major player in sonography - Biosound Esaote, makers of MyLab technology such as MyLab50, which can perform conventional and Doppler sonograms.
