Abstract:
A radiation device for comparatively determining a proportion of body materials defining a body part, said radiation device comprising:(a) a device for retaining therein said body part in a uniform position; (b) at least two reference materials having attenuation characteristics, said reference materials being positioned for said comparative determination during a simultaneous irradiation of said body part and said reference materials, and wherein said attenuation characteristics are selected in correspondence to said body materials; (c) a radiation means for simultaneously irradiating said body part and said reference materials thereby creating attenuated beams of said materials and said body part; (d) a detector to detect said attenuated beams as attenuated values of said materials and said body part; and (e) a calculating means for calculating said proportion of said body materials defining a body part based on said attenuated values of said materials and said body part.
