Researchers have developed a non-invasive technique for early detection of skin cancer.
The procedure uses different colors of light and assorted alignments of the electric field of each light segment to create unique images that can identify suspect skin growths called nevi.
"We are able to generate processed images that reveal the subsurface characteristics of the nevus," said developer Justin Baba of Oak Ridge National Laboratory. "It is our hope that these images will enable an accurate determination of whether the nevus is cancerous or benign."
