Abstract: A method for measuring skin thickness. The method includes at a first 3D point on an outer surface of a patient, exposing the first point to near infrared (NIR) energy from an NIR source. The method includes measuring reflected energy emanating near the first 3D point, or beam incident point. The method includes determining a pattern of the reflected energy based on a distance from a center of the reflected energy, wherein the center is approximated by the first 3D point. The method includes determining a skin thickness measurement based on the pattern.
