Exerpt from article on ivanhoe.com 6/03 Now, technology called photonics may help doctors detect skin cancer much sooner. Optical scientist Jannick Rolland, Ph.D., says it works similarly to ultrasound. "When you do ultrasound, you're measuring the time of the sound as you're imaging, where in optics, we're measuring, in a way, the time of the light to go through some tissue." Rolland, of the University of Central Florida in Orlando, demonstrates with an onion how infrared light is reflected off skin. The light travels through cables into a detector that scans the image into a computer. "If you have cancer, you could see how these layers are being deformed or cancelled out. So, we expect a layer here and we don't see that layer. Well, we know there's cancer being formed there," she says.
