摘要: Apparatus and method for use in conjunction with an X-ray apparatus, filtering scattered irradiation enhancing recordation of unscattered transmitted through a subject exposed to analysis beam. The apparatus includes grid mechanism including filtration strips which filter obstruct from detection, recording analog image the detector, converting equivalent digital image, reconstructing as if absorbed by were not obstructed detection. comprises projecting beam photons at be examined, aligning photon sensitive detector behind photons, detection absorptive strips, are or strips.
