About Diagnostic Medical Sonography

Diagnostic Medical Sonographers use high-frequency sound waves (ultrasound) to produce dynamic visual images of organs, tissues and blood flow inside the body.

Sonographers work closely with physicians by providing diagnostic images and a summary of technical findings to aid in reaching a medical diagnosis. This is a non-radiation modality, and it may be used on any patient, from unborn babies to the elderly. Sonographers may work in a hospital, a clinic, a physician's office, education, sales or as an applications specialist.

Daily tasks of the sonographer include:

  • Obtain and record an accurate patient history
  • Perform diagnostic procedures and obtain diagnostic images
  • Analyze technical information
  • Use independent judgment to recognize the need to extend the scope of the procedure, depending upon the diagnostic findings
  • Provide an oral or written summary of the technical findings to the physician for medical diagnosis
  • Provide quality patient care
  • Collaborate with physicians and other members of the healthcare team
