Abstract:
1. A method for the manufacture of a scintillator system comprising an arrangement of separate scintillator cells and an Anti-Scatter-Grid, the method comprising the following steps: a) cutting slots into a cylindrically shaped scintillator crystal, which has planar and parallel top and bottom surfaces, without dividing it into several pieces; wherein the top surface is structured with a rectangular pattern by cutting parallel slots in a first direction and cutting parallel slots in a second orthogonal direction; b) inserting plates of a radiation absorbing material into the slots; c) separating a layer containing the plates of the radiation absorbing material in the cut slots by a cut parallel to the top surface, wherein the remaining cylindrical scintillator crystal has a disk-shaped arrangement; and d) final cutting of the scintillator crystal such that the segments of the scintillator crystal forming the disk that project over the rectangular base of the plates of the radiation absorbing material are cut away, resulting in a required arrangement of separate scintillator cells.
