A medical doctor at Yale Medical School offers a demonstration of Sonivate Medical's SonicEye technology to see inside the body -- in this case, a purple slab representing a human arm. It's based on a wearable device that allows a user to both feel the patient's limb while providing digital guidance for treatment.

Sonivate is a young Beaverton company that has backing from the U.S. military and has won a couple of investment competitions. In January, it announced a partnership with Fukuda Denshi USA, an ultrasound systems company. Fukuda Denshi said it would distribute the SonicEye with its ultrasound products.
