A method of aiding in the evaluation of lesions in a body using a plurality of sets of image data of sections of the body region in mutually parallel planes. Processing of the data requires several steps, including pixel intensity pattern recognition, ˜ contouring of the regions of probable pathology, thresholding and 3-dimensional clustering, providing each pixel with a color representative of a selected opacity level and displaying an image of the region of interest where areas of probable pathological conditions are highlighted.
