Detector unit, x-ray computed tomography recording apparatus, X-ray detector, and method for producing an X-ray detector

A detector unit (40) for detecting X-rays which have passed through a collimator (30) having a plurality Kollimatoreinzelplatten (33), comprising: one at a Kollimatorhalterung (31) for supporting the collimator (30) to be attached to the substrate (41); a to the substrate (41) attached to the photodetecting device assembly (42) which is arranged in a channel and a layering direction (C, S) photodetecting conversion devices; provided one on the photodetecting device assembly (42) scintillator (43) having a plurality of scintillator segments which are arranged corresponding to the photodetecting conversion devices for converting the X-rays into light; and an engagement component (45; 48; 49) at the upper and lower ends of the scintillator (43) in the stacking direction (S), wherein the engagement component (45; 48; 49) respectively on the Kollimatoreinzelplattenseite of the substrate (41) provided for engagement portions (45a ; 48a; 49a) which 33) to be engaged (with the Kollimatoreinzelplatten to a position of the photodetecting device array (42) or of the scintillator (43) in the channel direction (C) relative to the Kollimatoreinzelplatten (33) set.
