Ultrasound is the use of reflected sound waves to image the structures of the heart in real-time motion. Using Doppler ultrasound, health care personnel can evaluate blood flow in the heart. These are the most commonly used imaging procedures for the diagnosis of heart disease.
Diagnostic cardiac sonographers use complex equipment to perform a variety of echocardiographic procedures using ultrasound technology. Echocardiography is a highly valuable diagnostic tool for the evaluation of the anatomy, function and hemodynamics of the heart and circulatory system. Cardiac sonographers work under the direction of a cardiologist.
Graduates in this field are in high demand for positions in hospitals, clinics and doctor’s offices. According to the US Department of Labor, Bureau of Labor Statistics Occupational Outlook Handbook, employment positions for diagnostic medical sonographers is expected to increase by about 18 percent through 2018 – faster than the average of all occupations. The demand for diagnostic imaging and therapeutic technology professionals is projected to increase over the next decade.
