Fig. 5. —Schematic diagram of proposed instantaneous CT unit (side view). Pyramidal reflector of mosaic crystals is used to split imaging beam into multiple beams that are reflected off central axis for some distance, then redirected through central axis by second-order reflection off multiple flat crystals, which send beam through object to be imaged and onto multiple detector areas on flat panel detector or onto multiple smaller detectors. Images obtained by this method can be used to reconstruct object three-dimensionally.
