Abstract: Systems and methods are provided for non-invasive detection of blood vessels. The systems and methods cool uniformly a tissue volume below a skin region for a specified cooling period and then image vessel thermal footprints of vessels below the skin as they heat up the skin region. The systems comprise a thermal imaging device configured to image the skin region after the cooling period, an image processor arranged to identify, in images captured by the thermal imaging device, which arise on the skin region after discontinuation of the cooling, and displaying means configured to present the identified vessel thermal footprints. The system and methods may analyze the spatio-temporal patterns of the natural heating of the skin surface to derive data on the location of the vessels under the skin. Three dimensional (3D) imaging optics and techniques may further enhance the vessel imaging.
