How are Ultrasounds performed?

An ultrasound procedure may be done on an outpatient basis, or as part of inpatient care. Although each facility may have specific protocols in place, generally, an ultrasound procedure follows this process:

  1. A gel-like substance will be smeared on the area of the body to undergo the ultrasound (the gel acts as a conductor).
  2. Using a transducer, a tool that sends ultrasound waves, the ultrasound will be sent through the patient's body.
  3. The sound from the transducer will be reflected off structures inside the body, and the information from the sounds will be analyzed by a computer.
  4. The computer will create an image of these structures on a television screen. The moving pictures can be recorded on film videotape.
  5. There are no confirmed adverse biological effects on patients or instrument operators caused by exposures to ultrasound.
