Ultrasound technology, also called diagnostic medical sonography—or simply sonography—is a medical diagnostic tool that uses high-frequency sound waves to generate images of a person’s internal organs, tissues and blood.
Using a small wand-like instrument called a transducer, sound waves are transmitted into a specific part of the body, and the returning echo waves are captured and converted into images. These images are known as “ultrasound scans” or “sonograms.” Doctors use ultrasound imaging to find abnormalities of the internal organs and diagnose illness, as well as to monitor the health of developing fetuses in pregnant women.
Ultrasound imaging is increasingly used to diagnose internal medical conditions because unlike other medical imaging techniques such as X-rays, CT (computed tomography) scans or nuclear medicine, ultrasound doesn’t use or emit radiation into the body. This makes ultrasound imaging a popular method for testing pregnant women and babies, who are at high risk for complications associated with radiation. However, there are many other ways in which ultrasound imaging is used to diagnose illness in the body.
Here is a list of common ultrasound technician education and career specialties:
Ultrasound technicians who obtain certification in more than one of the above areas are often considered especially valuable by potential employers since they only have to hire one technician to perform multiple procedures in multiple departments. Ultrasound imaging offers well-paid, stable and rewarding careers.
