What does a Sonographer do?

Sonographers (ultrasound technologists) use complex equipment to direct high frequency sound waves into specific body areas to produce images that show the shape and position of fetuses, internal organs, fluid accumulation or masses. These images are used by physicians to make diagnoses. Many sonographers, especially those who work in large institutions, specialize in examining specific areas of the body. Examples include neurosonology (brain), echocardiography (heart), obstetrics/gynecology (female pelvis) and vascular (arteries and veins). Sonographers work under the supervision of a physician or senior sonographer.

What might a Sonographer do in a workday?


  • check patients’ medical histories and prior test results.
  • select and set up appropriate test equipment.
  • plan procedures and explain them to patients.
  • determine the proper patient position and transducer selection to achieve accurate test results.
  • complete the scan while observing the screen to make sure that the image produced is satisfactory for diagnostic purposes.
  • operate equipment that produces photographs or printout (ultra-sonograms) images.

Sonographers may work in a laboratory, an examination room, at bedside or in surgery.
