    Noncontact Laser Ultrasound Safely Images Human Tissue

    Article obtained from Photonics RSS Feed.

    MIT engineers have devised an alternative to conventional ultrasound imaging that doesn’t require contact with the body and can be used on patients who may not tolerate a probe on their body, such as infants, burn patients, or patients with sensitive skin. In tests scanning the forearms of volunteers, the researchers were able to observe common tissue features such as muscle, fat, and bone down to about 5 cm below the skin. The images, comparable to conventional ultrasound, were produced using remote lasers focused from half a meter away.

    Since sound waves travel farther into the body than light, the researchers began by investigating how to convert a laser beam’s light into sound waves at the surface of the skin, in…
