vibro-acoustography imaging
(VY-broh-uh-koos-TAH-gruh-fee IH-muh-jing)
A technique being studied in the diagnosis of breast cancer and other types of cancer. Vibro-acoustography imaging uses ultrasound (high-energy sound waves) to cause tissues to vibrate. The sound made by the vibrating tissues is picked up by a microphone and is used to make an image of the object on a computer. Cancer tissue can be seen because it is denser and vibrates at a different rate than normal tissue.
