Abstract

A prototype instrument (MAVIS) has been built which measures the area and volume of wounds with a precision of 5% and without making physical contact. MAVIS measures area using a calibrated video image, and measures volume using the method of structured light which determines the depth of a wound by the distortion of projected, parallel stripes. The volume is that trapped between the base of the wound and the reconstructed original healthy skin. The main source of imprecision is the need for the operator to trace manually the perimeter of the wound. Image processing algorithms based on active contour models are being developed to illustrate this process
