Skin scan: NIR cancer mapping
Date: Oct 1, 2012
Author: David Bradley
Non-invasive mapping of the network of tiny blood vessels beneath the skin is now possible thanks to an advanced optics system and near-infrared imaging. The new technique could one day be used to quickly and efficiently reveal the latent signs of skin disorders, such as psoriasis or even skin cancer.
