Ultrasounds are an important feature of technology used in our world today. The medical world uses ultrasounds and x-rays on an everyday bases. Ultrasounds are high-frequency sound waves and ultrasounds also produce sound waves that are beamed into the body causing return echoes that are recorded to visualize structures beneath the skin. Ultrasounds have thousands of different types and help doctors and patients see specific diseases and conditions that they cannot see otherwise. However, even though ultrasounds benefit people, many wonder if ultrasounds may have bad effects too. Many wonder how do ultrasounds truly work. Ultrasounds are actually more complex than what they seem to be. First, the ultrasound machine transmits …show more content…
Countless numbers of people have contributed to the growth of ultrasound technology over the years; however two men took a very large part at the beginning of this growth. Doctor Karl Theodore Dussik of Austria was a man who helped the growth of ultrasound. He published the first paper on medical ultrasonics in 1942, and he based the research on transmission ultrasound investigation of the brain Professor Ian Donald of Scotland was another person who tried to help the growth of ultrasounds. Donald helped developed practical technology and applications for ultrasound in the 1950s ("The history of," 2011). Ultrasounds are an easy procedure. The patient can easily just sit back and relax while the doctor takes the lead. Preparation for ultrasound is minimal. Generally, if internal organs such as the gallbladder are to be examined, patients are requested to avoid eating and drinking with the exception of water for six to eight hours prior to the examination (Shiel, 2011).This is because food causes gallbladder contraction, minimizing the size, which would be visible during the ultrasound. In preparation for examination of the baby and womb during pregnancy, it is recommended that mothers drink at least four to six glasses of water approximately one to two hours prior to the examination for the purpose of filling the bladder. The extra fluid in the bladder moves air-filled bowel loops away from the womb so that the baby and womb are more visible during the
The Diagnostic Sonography more commonly known as Ultrasound is a medical procedure in which you use high frequency sound waves to produce visual images of organs tissues or blood flow inside the body. Ultrasound is regularly known as the procedure used to examine women who are expecting. Although, Sonography is used in many different ways other than for expectant mothers. Sonography is also used to detect such things as heart disease, heart attacks, and vascular disease that can lead to stroke. (SDMS, 2010) Moreover, Sonography is also used to examine breasts, abdomens, female reproductive systems,
Being able to identify lumps, swelling, tissue damage, cysts, and the overwhelming news of the sex of a baby all have something in common, an ultrasound. Swelling of the spleen, kidney stones, blood clots, aneurysms, cancer and so much more can be identified through the works of an ultrasound’s imaging technique. Ultrasound involves many concepts, procedures, and careers. The amount of medical possibilities involved with ultrasounds is useful in major medical diagnostics. The field of ultrasounds and career opportunities are widely growing. As medical careers flourish, needs for technicians in many fields of medicine are increasing. Instead of a doctor choosing complex and risky surgery to find out problems within the body, they can now
* Ultrasound. An ultrasound uses high-frequency sound waves to generate images of your internal organs, such as your kidneys and bladder, on a computer screen.
Ultrasound imaging has many uses in medicine, from confirming and dating a pregnancy to diagnosing certain conditions and guiding doctors through precise medical procedures
Another form of imaging is ultrasound. Ultrasound, which uses very high frequency sound, is directed into the body. And because the tissue interference's reflect sound, doctors are able to produce, by use of a computer, a photograph or moving image on a television. Ultrasound has many application uses on the body, but is more commonly used in examinations of the fetus during pregnancy, because use of radiation may affect the outcome of the baby. Some other practices for ultrasound include examination of the arteries, heart, pancreas, urinary system, ovaries, brain, and spinal cord. And because sound travels well through fluids it is a very useful technique for diagnosing cysts( which are filled with fluid), and fluid filled structures such as the bladder. And since sound is absorbed by air and bone it is impossible to use a ultrasound on bones or lungs.
Dr. Fox is an emergency physician at UCI Medical Center, treating and diagnosing patients using an ultrasound. His scope of research involves looking at patients’ internal organs via ultrasound, which is much quicker and less harmful than using x-ray scans that are traditionally used in emergency departments. He is also a part of the American Institute of Ultrasound in Medicine (“Faculty and Staff”). Dr. Fox is also a director of instructional ultrasound and is the assistant dean at the UCI School of Medicine (“John Christian Fox”). He started an ultrasound rotation at the UCI School of Medicine, and with a grant given by SonoSite, Inc., the ultrasound curriculum is now embedded within the UCI School of Medicine curriculum (“Faculty and Staff”). He went to Tufts University School of Medicine, receiving his MD in 1997 (“John Christian Fox”). His main research focus is to try to incorporate ultrasound more into the emergency department, and tries to find revolutionary ways to utilize ultrasound, especially because it is very cost-efficient and images are seen real-time, unlike MRI scans or x-rays, which can emit harmful radiation or results take much longer to acquire. Eric Viquez is one of the Bio 199/EMRAP (Emergency Medicine Research Associates Program) students in Dr. Fox’s ultrasound lab. He is currently a 4th year undergraduate biological sciences major who is going to medical school in the fall; he shadows shifts with Dr. Fox and
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
Over the last few years ultrasound technicians as a career has upgraded a lot because of the advancements in the technology. We have learned besides seeing what is going on inside the body we can use the sound waves, that ultrasound technology used to produce the image, to provide therapy to correct a problem which Emma Lloyd talks about in her article Benefits of

Sonography utilizes sound waves to generate an image that can be analyzed to determine or rule out a diagnosis. Ultrasound or ultrasonography is a medical imaging technique that uses high frequency sound waves. It is a high pitch frequency that cannot be heard by the human ear. A diagnostic medical sonographer works directly with patients in a dimly lit room with imaging machines. The sonographer gets the medical history of the patient and prepares the patient for an ultrasound examination. The sonographer explains the noninvasive procedure and answers any question the patient might have. The sonographer positions the patient and covers the patient only exposing the area needed for the procedure. The sonographer
Diagnostic medical sonographers play a key role in the health care team and often work alongside doctors, nurses, and other technologists. They prepare patients by explaining the procedure and collect necessary patient history information prior to examination. An ultrasound is then performed, which is a non-invasive process that enables sonographers to send high-frequency sound waves into the body. The return signals are then analyzed to help visualize internal organs in 2D, 3D or 4D. These images help physicians with medical diagnoses and are also used for monitoring pregnancy. An ultrasound is often executed on many different areas of the body including the abdomen, pelvis, tissues, and vascular and cardiac systems. A DMS may also be required
A diagnostic medical sonographer is also known as an ultrasound technologist, or simply a sonographer. They use high-frequency sound waves, which are an offshoot of World War two sonar technology, to produce images of the internal body (“Diagnostic” 162). This picture is shown when the sound waves bounce off the internal body, and then become echoes that are now displayed as a two-dimensional black and white image on video. These images are then studied by a physician who studies the function of organs. A sonographer not only completes procedures for pregnant women as it is most known, but also for cysts, abdominal tumors, and the functions of blood vessels and heart valves.
Contraindications for ultrasound must be taken into consideration when treating patients. Over the years, ultrasound has been utilized and at times, used with negligible risk. However, this depends on the part of the body being treated. Therefore, a clinician must take every patient into consideration when administering therapeutic ultrasound. It is also equally important to be cautious of the patients’ safety. There are risks when using ultrasound therapy machines that the patient must be made aware of. These machines can cause substantial bioeffects and deliberate caution must be taken to lower the risk of injury for each individual patient (J Ultrasound Med, 2012, p. 10). This is also true when treating a pregnant woman. An embryonic and fetal when exposed to a situ temperature above 41C (4C above normal temperature) for 5 min or more could be potentially hazardous (International Congress Series 1274 (2004) p. 126)

Ultrasound or ultrasonography is a medical imaging technique that uses high frequency sound waves. It is a high pitch frequency that cannot be heard by the human ear. In ultra sound the following happens: High frequency sound pulses (1-5megahertz) are transmitted from the ultrasound machine into your body using a probe. The sound wave will travel into your body until it hits an object such as soft tissue and bone. When the sound wave hits these objects some of the wave will be reflected back to the probe. While some waves may carry on further till they hit another object and then reflected back. The probe picks up these reflected sound waves and relays them to the machine. The distance and time from the probe,
