Claim One:
1. Apparatus comprising: a configurable scanner and a processor, the configurable scanner adapted for contactless measurement of volume of a wound on a target body part, said scanner comprising: a scan head comprising a line-laser projector and an image capturing device; said projector operable to produce a contour line on the target body part and said image capturing device having a field of view inclusive of said contour line; a scanning mechanism for translating the scan head along a motion path, said motion path being substantially semicircular and having a configurable radial distance from an imaginary axis; a positioning mechanism for locating the scan head proximate to the target body part such that the imaginary axis is approximately coincident with an axis of the target body part; and means for calibrating the positioning mechanism and the scanning mechanism responsive to a feature of the target body part; the processor operable to control a scanning procedure, said procedure comprising: operating the scan head so as to project a contour line onto the surface of the target body part, said contour line having a calibrated length; storing an image of the projected contour line captured by the image capturing device said image comprising a plurality of pixels; and moving the scan head a distance along the calibrated motion path and repeating said operating step; and the processor further operable to analyze each captured image to determine the coordinates in three axes of at least one pixel of the projected contour line, said analyzing step comprising a calculation based on a known geometric relationship between the laser projector, the calibrated line length and the image capturing device; create a 3D model of the region of interest; and determine a volume of the wound from the 3D model.
