FIELD: medical engineering. SUBSTANCE: method involves building three-dimensional computer image of a biological object when scanning coordinate table with minimum step in high resolution mode in keeping patient body immovable until complete set of tomograms is produced. Data for restoring bone structures of given density are selected from tomographic data array by defining cut-off level based on intensity gradient coefficient value enclosed between 0 and 225 to enable one to build stereo lithographic model. EFFECT: accelerated operation; satisfactory cosmetic result. 10 dwg, 2 tbl
