| Drawing on sonar technology, sonography uses sound waves to see inside the body. This program visits Thomas Jefferson University Hospital to study how sonographers put this technology into practice. An ultrasound scan is done on a middle-aged man and on an expectant young mother, and the results are reviewed and explained. The subspecialties of sonography—general ultrasound, vascular ultrasound, and echocardiography—are also explored from a career perspective, and the growing demand for sonographers is discussed.
