A new method is presented for “extending” 2D radiographs into the third dimension. Pixel grey values, reflecting X-ray intensity losses, are converted into average attenuation co- efficients, and the latter are related to vascular porosities in cortical and trabecular bone. These conversions contain in- formation on cortical and overall mandibular thicknesses, pixel-specific bounds for which can be finally assessed from the pixel brightness. Computed thickness profiles al- low for localizing potential abnormalities in the mandible, as incentive for further, targeted examination.
