The Diagnostic Medical Sonographer provides the supervising physician (sonologist) with diagnostic medical images and physiologic data by use of high frequency sound waves (ultrasound) to produce dynamic visual images of organs, tissues, or blood flow inside the body.

Sonographers have extensive, direct patient contact that may include performing some invasive procedures. They must be able to interact compassionately and effectively with people who range from healthy to critically ill. Sonographers must be able to communicate and collaborate with physicians and other members of the health care team to provide the highest quality patient care.
