1. A method of calculating a thermal path in a living body, comprising: operating a thermospatial imaging system for imaging the body and generating and storing in a memory a synthesized thermospatial image defined over a three-dimensional spatial representation of the living body and having thermal data associated with a surface of said three-dimensional spatial representation; retrieving said thermospatial image from said memory; identifying by an image processor, at least one thermally distinguishable spot in said thermospatial image and storing the at least one thermally distinguishable spot in a memory; and by said image processor, using said thermospatial image and said thermally distinguishable spot for calculating the thermal path and generating an output indicative of the thermal path, wherein said thermal path is calculated by calculating a spatial gradient of said surface at said spot.
