The photo on the right shows a medical technician using an ultrasound machine to diagnose appendicitis to a patient, without the use of x-rays. The ultrasound imaging technique involves using high frequency sound waves and their echoes. The machine transmits high-frequency sound pulses into the patient’s body using a probe. In the image, the technician presses and moves the probe along the patient’s body. This photo was taken in the St. Louis Children’s Hospital.
A wave is a traveling disturbance that carries energy from one place to another. Ultrasound-imaging machines use waves to produce real time images of patients’ organs and tissues to complement diagnosis. The frequency of a wave refers to the number of waves passing a point at a certain time. An ultrasound is a type of wave that has a frequency exceeding the upper limit of human hearing (greater than 20,000 hertz). However, diagnostic ultrasound machines usually use frequencies in the order of 1-10 million hertz. The frequency of waves is very important, as it is very specific when using these instruments. It is imperative to consider that the speed of sound depends on the specific properties of a medium. Therefore, these concepts must be taken into consideration when manufacturing and getting prepared to use such instruments. The wavelength is the distance between two identical peaks in the wave cycle. It is one of the main factors that affect the resolution of an ultrasound image. As the wavelength of a wave
The primary focus of a Diagnostic Medical Sonographer is to create images by using a high-tech instrument which will take images from inside the human body that will be used by doctors to make a medical diagnosis (Society of Diagnostic Medical Sonography, 2015).
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.
An ultrasound is also referred to as a sonogram. It uses a high frequency sound waves to create images of the inside of the body.
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.
Sonography is a non-invasive medical procedure that uses the echoes of high-frequency sound waves to construct an image of internal organs or body structures. The employment rate is is expected to grow 26 percent from 2014 to 2024. Since ultrasound is non-invasive, it is more encouraged than other methods so the career is always in demand. Diagnostic medical sonographers duties are to prepare and maintain diagnostic imaging equipment, taking a patients medical history, answering questions about the procedure, operating the equipment, review images and test results, know the difference between normal and abnormal images, analyze diagnostic information, record findings, and keep track of patient records. Hospitals, offices of physicians, medical
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
The increasing demand for diagnostic imaging and therapeutic technology promises an exceptional outlook for sonographers. The majority of diagnostic medical sonographers are employed by hospitals, but accessibility to low-cost portable ultrasound equipment has led to a growing number of career opportunities at clinics and diagnostic centers (Rising Demand for Diagnostic Medical Sonographers). They now have access to portable units as small as laptop computers making commuting from hospital bedsides to clinical practices easier. Since some sonographers make their own schedules through contracts with clinics, these portable units make traveling much more convenient.
Diagnostic medical sonographers who are also known as ultrasound technologists, play a very pivotal role in the health industry. Sonographers use specialized 3D imaging machines to generate images of internal body organs and structures which works hand-in-hand with doctors in gathering the necessary data needed for a diagnosis (Reece & Hobbins, 2007). Diagnostic medical sonography has many different branches you may pursue such as obstetrics/gynecology, breast sonography, cardiovascular sonography, and abdominal sonography to name a few (Brent, Jensh, & Beckman, 1991). The limits of authority and legislated scope of practice for sonographers has recently been revised in May 2013 by sixteen representatives from multiple sonography organizations throughout the country (2016). A diagnostic medical sonographer must be a qualified individual who is academically credited as well as clinically skilled before they begin to practice. Affirmation, demonstration, continuing education as well as re-certification from a nationally accredited organization is required for every sonographer (2016).

To achieve my goal to attend Johnston Community College’s Medical Sonography program I have to start by completing an application for general college admission. After completing the admission process I will then have to start on my classes that are required for me to be accepted into the program. Once I fit the requirements for the program I will then I will then I will sign up for the Medical Sonography program, which should take about two years. To successfully reach my goal I may have to cut back on the hours that I take at my part time jobs. At the moment I have a lot of free time which allows me to have two job, once I begin working on my goal I expect to be forced to either quit one of my jobs or to cut back on my hours.
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

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,
