Recommended: History of ultrasonic
Ultrasounds have been around and in use for centuries, continually revolutionizing the medical field. They incorporate advanced technology and science into highly functional medical machinery. Throughout the years, scientist have found a way to develop a modernized version of this classic medical device by introducing three-dimensional technology. Three dimensional ultrasounds, although advanced and modern, have a number of noteworthy disadvantages.
In 1980, Olaf von Ramm and Stephen Smith introduced the three-dimensional ultrasound into the medical field. Eventually, in 1987, they were granted a patent. Since then, the use of this device has grown tremendously; however, it still is not used as often as the traditional two dimensional

Once these waves have reached an organ or other internal body structure, they are sent back to the probe. This is where they are analyzed and translated back into the computer. By using the speed of sound, the computer is able to calculate the distance, size, shape, and density of the organ (Gurnick Academy of Medical Arts). The numerous two dimensional images are able to be combined, thus creating a more detailed, three dimensional image (Jeandron). This technology is analogous to that portrayed by the navigation system of submarines and sonar bats (Gurnick Academy of Medical Arts).
Ultrasounds are most commonly used for viewing internal organs, analyzing blood flow, and checking on a developing fetus (Freundenrich). By simply using the speed of sound and a computer monitor, doctors are able to easily view and assess the movement and functionality of tendons, ligaments, muscles, and joints (Gurnick Academy of Medical Arts).
Within the last century, as three dimensional ultrasounds have become more popular, the images have been viewed as “baby keepsakes” (Stenson). Because the three dimensional image is very detailed, and even shows physical features of the baby, this has become a popular thing to have

Professionals generally suggest that people do not receive three dimensional ultrasounds for purposes not medical related (FDA). For example, there have been many cases in which women simply want to see what their baby will look like, and use the image as a keepsake, as mentioned previously. However, professionals suggest that three dimensional ultrasound should strictly be used as a way to further analyze concerning and potentially dangerous aspects in the fetus. The reason for this is that according to the American College of Obstetricians and Gynecologists, subjecting the human body, particularly a fetal boy, has been proven to cause “jarring vibrations and a rise in temperature” (FDA). Although the FDA notes that these effects have not directly harmed a fetus, they are certainly serious risks that occur in a three dimensional ultrasound.
In addition, the three dimensional ultrasound takes much longer to complete, as it is a series of traditional two dimensional ultrasounds in a row. This also causes an increase in the amount of time the fetus is subjected to the harsh sound waves; thus, posing the recurring issue of potential harm to the unborn
According to Diaz (2008), the results from the study showed that the images from the new 3D technology were far clearer and more defined when compared to the US-A traditional device. In muscle contusions and lesions of the tendons, the definitions of hemorrhaged areas increased dramatically. The images from the chronic ligament injuries showed where the scar tissue had formed and provided a better visualization of the damaged tissue. Finally, the new US-B system allowed the ultrasound specialist to see the contents of the bursa sac and thickness of the walls more clearly.
I have always been fascinated with the medical field ever since I was little, my first choice for electives were always health science and anatomy classes. After my cousin, Deanna, had her first child and receive her first ultrasound, I knew that was what I wanted to do for the rest of my life. The ultrasound technician had made her feel so comforted and just made the entire experience enjoyable for everyone; I’m eager to be able to start my life with a job that I know I will love. Anytime that I meet someone who is in the field themselves, I always ask questions and listen to what they do throughout the day to get some real insight on what being a technician really entails.
During pregnancy an echocardiogram of the fetus can be done to produce images of the heart by sending ultrasonic sound waves to the vital organ. These sound waves create an image for the physician to analyze the babies heart function, structure sizes, and blood flow. A positive diagnosis before birth has shown to improve chances of survival, and will allow for appropriate care to be readily available at birth. If a baby is born without being diagnosed with the heart defect, some symptoms previous noted such as low oxygen levels can be suggestive of hypoplastic left heart syndrome. The baby may not display any symptoms or signs for hours after birth because of the openings allowing for blood to be pumped to the rest of the body. However, listening to the babies heart can revel a murmur indicating an irregular flow of blood in the heart. If a murmur is heard, or signs of the defect are observed, diagnostic tests will be ordered and performed. An echocardiogram is still the go-to test once the baby is born to evaluate the heart. The echocardiogram will diagnose the newborn, by revealing the underdeveloped left ventricle, mitral and aortic valve, and the ascending aorta commonly seen in

Diagnostic medical sonography is a profession where sonographers direct high-frequency sound waves into a patient’s body through the use of specific equipment to diagnose or monitor a patient’s medical condition. As described by the Bureau of Labor Statistics, this examination is referred to as an ultrasound, sonogram, or echocardiogram. The high-frequency sound waves emitted from the handheld device, called a transducer, bounce back creating an echo and therefore produce an image that can be viewed on the sonographers computer screen. This image provides the sonographer and physician with an internal image of the patient’s body that will be used in the diagnosis. The most familiar use of ultrasound is used in monitoring pregnancies and is provided by obstetric and gynecologic sonographers, who also provide imaging of the female reproductive system. Other types of sonography include; abdominal sonography, breast sonography, musculoskeletal sonography, neurosonography and cardiovascular sonography. Due to the vast nature of uses in sonography, most professionals study one field that they choose to specialize in. Diagnostic medical sonography is a rapidly growing field because of the increase in medical advances. The area of Cleveland, Ohio has continued to rise in the medical field with great strides, providing better career prospects with the availability of numerous employment positions.
The current demand is high for sonographers throughout the United States and abroad. It has been shown that the demand for sonographers will continue to increase well into the future. According to the Bureau of Labor Statistics (BLS), the employment in the field of Medical Sonography is predicted to grow 45.5% between 2010 and 2020. The growth is among the fastest rates in all healthcare jobs. As a result, as the demand grows for sonographers, so will the salaries (BLS). The attractive salaries and flexible work hours, as well as the diversity of options available and the lack of geographical limitations on employment opportunities, make Ultrasound an attractive career field (BLS). Most employers prefer to hire diagnostic imaging workers with professional certification. Also many insurance providers and Medicare pay for procedures, but only if certified. According to the BLS, Medical Sonography is on its list of the best jobs of 2013. Medical Sonographers can get promoted by certifying in more than one area in ultrasound or having more work of experience being promoted to a supervisor. Anywhere you go this job has a high demand and a fast rate. Due to population hospitals, facilities, or offices will always need medical
In general, ultrasound waves produced by an instrument called transducer are sent into a patient. Some of the waves are absorbed, but the other portion of these waves are reflected when tissue and organ boundaries are encountered. The echoes produced by the reflected waves are then picked up by the transducer and translated in a visible picture often referred to as ultrasound. In the paragraphs that follow, the physics of how the transducer functions, what the ultrasound waves do, and how the image is formed will be explained.

Ultrasound Technicians are very valuable in the world of health care. Also known as Diagnostic Medical Sonographer, an Ultrasound Technician uses special machines and equipment that operates on sound waves to determine or diagnose medical problems for patients. There are specializations within this field in which some individuals explore. For instance, areas of specialization includes but not limited to; pregnancy, heart health, gynecology, and abdominal sonography. Although each specializing branch has its own distinctive function, they all involve probing the body to facilitate doctors with diagnoses.
It is a requirement for the American Registry for Diagnostic Medical Sonography. Employers prefer these individual skills given in the ARDMS. I will study skills and concepts in medical assisting, medical billing, coding, laboratory procedures, phlebotomy, nursing assisting and pharmacy technology. (California College San Diego, 2015) Having extra skills in many other careers will help me be successful in many other things in life. Some other benefits is that once I graduate I could be prepared for a career as a pharmacy technician, certified nursing assistant, home health aide, medical receivables and a coding professional. (California College San Diego, 2015) It makes it interesting because I’ll be able to be qualified for other things. These skills and benefits will make sure that I’m able to do whatever I desire. Becoming an ultrasound technician will make a difference in the world because I’ll be able to find major things out before they become
There is also a high-resolution ultrasound scanning that can detect chromosomal and physical abnormalities in the first trimester as opposed to the second trimester. A technology such as this can create many ethical problems. Mcfadyen describes the biggest problem as being informed consent. “They may believe that it will provide information only about gestational age and be unaware of the range of abnormalities that can be detected. Recent research suggests that many women are not told beforehand of the first scan’s potential to detect fetal anomalies.”
[IMAGE] * Ultrasound Ultrasound was another application of physics which I saw in QueensElizabethHospital . The use of ultrasound which I saw was the ultrasound scan. This is mainly used for pregnant women to see if the foetus has any abnormalities, or check on progress and growth. The rays in ultrasound have a very high frequency which is above the human audible range. Here you can see an image made using ultrasound to see a foetus's progress, growth and if the foetus has any abnormalities.[IMAGE] Gamma camera.
Anatomists, morphologists and biologists have tried to understand the way living creatures are living, and what they look like inside. Dr. Frourie in 1974 painfully cut organisms into thin slices, to study their internal arrangement to better understand them. Today, these people use CT scanners instead. It is a lot easier, less bloody, takes shorter time and the sample is not affected or destroyed during the procedure- the advantages are numerous. This technique enables us to visualize the inside of us humans, organisms or other objects in 3-D geometry.
Images of human anatomy have been around for more than 500 years now. From the sketches created by Leonardo da Vinci, to the modern day Computed Tomography (CT) or Magnetic Resonance Imaging (MRI) scan, images have played a great role in medicine. Evolution in medical imaging brought together people from various disciplines such as Biology, Physics, Chemistry and Mathematics, a collaboration which has further contributed to healthcare as a whole. Modern day imaging improves medical workflows by facilitating a non-invasive insight into human body, accurate and timely diagnostics, and persistence of an analysis.
Initially, my area of interest was directed towards diagnostic sonography, however, this area of study was not
