Abstract
The present invention pertains to a device and method for imaging of a human foot including a transmissive sheet with an upper surface configured to accommodate a sole of the foot, a light source positioned below the sheet for emitting light toward the sheet, and an optical path controller in the sheet or coupled to the sheet for altering a path of the light causing internal reflection of the light toward a predetermined region of the foot. The image can be analyzed for a predetermined characteristic associated with a human patient, and determination made whether the characteristic in the image matches the patient. Brightness in the image can be analyzed for tissue moisture information.
