The trained eye of a dermatologist can identify many types of skin lesions, but human sight only goes so far. Now an international team of researchers has developed an advanced optics system to noninvasively map out the network of tiny blood vessels beneath the outer layer of patients' skin, potentially revealing telltale signs of disease. Researchers from Medical University Vienna (MUW) in Austria and the Ludwig-Maximilians University in Munich, Germany, used a technique called optical coherence tomography (OCT) to "see" beneath the surface of skin. Ophthalmologists have used OCT since the 1990s to image different parts of the eye and the technology has recently attracted increased interest from dermatologists.To see more details visit, www.sciencedaily.com
