NIR imaging can be used to find vessels under the skin

Application of Near-Infrared Imaging

NIR imaging can be used to monitor wound healing and to find blood vessels under the skin+

(λ = 685, 780, and 830).

Application of Near-Infrared Imaging

Currently used NIR cameras are expensive

Medical Near-Infrared Cameras

The purpose of this study is to manufacture a cheap near-IR camera and application for use with smart phones to test whether the device can detect areas of skin at risk for ulceration.
