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: A
gel-like substance will be smeared on the area of the body to undergo
the ultrasound (the gel acts as a conductor). Using a transducer, a tool
that sends ultrasound waves, the ultrasound will be sent through the
patient's body. 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. The computer will create an image of these
structures on a television screen. The moving pictures can be recorded
on film videotape.
