Diagnostic medical sonographers use special imaging equipment that directs sound waves into a patient’s body (in a procedure commonly known as an ultrasound, sonogram, or echocardiogram) to assess and diagnose various medical conditions. Most diagnostic medical sonographers work in hospitals. Some work in physicians’ offices or imaging clinics. Sonographers may be on their feet for long periods and may need to lift or turn disabled patients.
Diagnostic ultrasound uses high-frequency sound waves to produce images of the inside of the body. The sonographer presses an instrument called an ultrasound transducer to the parts of the patient’s body that are being examined. The transducer emits pulses of sound that bounce back, causing echoes. The echoes are then sent to the ultrasound machine, which processes them and displays them as images. Some responsibilities of a diagnostic medical sonographer include:
Diagnostic medical sonographers specialize in different parts of the body. The following are examples of specific types of sonographers: - Abdominal sonographers specialize in imaging a patient’s abdominal cavity and nearby organs, such as the kidney, liver, gallbladder, pancreas, or spleen.
Diagnostic medical sonographers need formal education, such as an associate’s degree or a postsecondary certificate. Many employers also require professional certification. Colleges and universities offer both associate’s and bachelor’s degree programs in sonography. One-year certificate programs also are available, although these are usually useful only to those who are already employed in related healthcare jobs, such as nursing. Employers prefer a degree or certificate from an accredited institute or hospital program. The accredited programs usually follow a specific course of study and include clinical training. These programs also include courses in medical terminology and interpreting sonographic images. Most programs are divided into the specialized fields that correspond to the relevant certification exams, such as abdominal sonography or breast sonography.
Some sonographers graduate with a degree in radiologic technology or nursing and then receive on-the-job training by their employer. High school students who are interested in diagnostic medical sonography should take courses in anatomy, physiology, and mathematics. Most employers prefer to hire sonographers who have professional certification. A sonographer can get certification by graduating from an accredited program and passing an exam. Most exams relate to the specialty that the sonographer is most interested in—for example, an exam to be become certified in abdominal sonography.
Diagnostic medical sonographers must follow precise instructions to obtain the images needed to diagnose and treat the patient. They also must pay attention to the screen while scanning a patient's body because the cues that contrast healthy areas with unhealthy ones may be subtle. To get quality images, diagnostic medical sonographers must be able to move equipment on the patient’s body in response to what they see on the screen. Diagnostic medical sonographers must work closely with patients. Sometimes patients are in extreme pain or mental stress, and the sonographer must get cooperation from the patient to create usable images. Diagnostic medical sonographers work on their feet for long periods and must be able to lift and move patients who need assistance. Diagnostic medical sonographers must understand how to operate complex machinery and computerized instruments.
Diagnostic medical sonographers do most of their work at diagnostic imaging machines in dimly lit rooms, but they may also perform procedures at patients' bedsides. Sonographers may be on their feet for long periods and may need to lift or turn patients who are disabled.
