Ultrasound in depth
What is an ultrasound scan?
Ultrasound is similar to the sonar that submarines use to navigate underwater. The ultrasound machine emits vibrations that enter your body and then echo back. These echoes create the ultrasound image. The frequency of the vibration is just above the frequency of audible sound, which is why we use the term "ultra" in ultrasound. These vibrations are so gentle that they cannot be felt, and have no known harmful effects.
For standard diagnostic ultrasound there are no known harmful effects on humans. Ultrasound imaging uses no ionizing radiation.

Each radiologist at Mass General Imaging is a specialist in a particular area of the body. Department of Radiology Chairman Emeritus James H. Thrall, MD, explains how patients benefit from the additional specialty training our physicians have completed.
