Health Diagnostics: Skin Perfusion Photography

Skin Perfusion Photography: Perfusion is the process of delivering blood into tissue. Measuring skin perfusion is important for wound and burn estimation, and for monitoring plastic and reconstructive surgeries. Here, we integrate computational photography with skin perfusion measurements via laser speckle contrast imaging (LSCI). By recording multiple images, we compute the direct scattering of laser light from the skin and eliminate unwanted scattering from the underlying tissue. Our method holds promise for many applications of precise analysis of in vivo blood flow.
