How It Works

Ultrasound is commonly used to
capture dynamic images of the
abdomen, the breast, the male
and female reproductive systems,
kidneys, thyroid, the developing fetus
and most recently, superficial tendons.
It is also an effective method for
capturing images of blood vessels,
vascular structures and the heart.

An ultrasound is also sometimes called sonography or ultrasonography. This technology bounces high-frequency sound waves off parts in the body and captures the returning echoes as images. The measurement of the sound wave relates to the distance and density of the imaged material.
