Washington University scientists have discovered a new time-reversal technology that allows researchers to better focus light in tissue, such as muscles and organs. Current high-resolution optical imaging technology allows researchers to see about 1 millimeter deep into the body. Beyond that, the light scatters and obscures the features, which is why we can't see bones or tissue in the hand with a flashlight. To overcome this, Wang and his lab developed photoacoustic ...
