What do they do?

Diagnostic Medical Sonography is a branch of radiology.

Sonography equipment directs non-ionizing, high frequency sounds waves into areas of a patient’s body to collect reflected echoes that form an image. A physician interprets the image to diagnose a variety of diseases and conditions.

Working under the supervision of physicians, diagnostic medical sonographers:

  • Gather, review and integrate patient histories and data
  • Instruct and care for patients
  • Record anatomic, physiologic and pathologic data
  • Process sonographic data
  • Maintain and operate sonography equipment
  • Uphold professional standards and ethics
