What does an abdominal ultrasound machine do, and how does it work?

ANSWER

The ultrasound machine sends out high-frequency sound waves that reflect off body structures, sending them to a computer that creates a picture of organs and structures in the abdomen, or belly. This is done with a handheld probe, called a transducer, which is moved over the abdomen. You’re not exposed to radiation with this test.
