Ultrasound

Ultrasound is a non-invasive imaging technique using high frequency sounds, well above the range of human hearing, to create images of soft tissue organs in the body. During an ultrasound, sound waves are transmitted into the body creating cross-sectional images as they echo off various organs.

Ultrasound does not use ionizing radiation. As the sound waves associated with ultrasound cannot travel through bone or air, it is not suitable for imaging the lungs, stomach, bowels, or bones.
