Abstract

A clinical instrument called a "Nevoscope" is used to image skin-lesions. The lesion is transilluminated by a fiber-optic annular ring light source that directs light into the skin area surrounding the lesion and thus forming a virtual source just beneath the lesion. Mirrors uniformly spaced around the lesion and tilted at various angles, provide orthographic projections of the skin lesion. Additional views are obtained by rotating the mirror assembly. These multiple views are used in a direct 3-D reconstruction of the lesion to estimate its depth of penetration. A pigment pattern analysis is performed on the direct view. This includes both color and texture segmentation. In this paper, we present preliminary results of our 3-D reconstruction and pigment pattern analyses of some lesions.
