摘要

The present invention relates to a process for the preparation of a collimator module as well as a collimator bridge and a collimator modules, a collimator bridge, a collimator and a tomography device. According to the invention, a collimator module for a radiation detector has a large number of collimator layers on. This collimator layers each have a flat grating structure on. The inventors have recognized that, the collimator module with a particularly high degree of accuracy is produced when a first collimator layer a retention structure and the collimator layers by the retaining structure on a first holding tool to be aligned relative to one another. This is because, with such a holding structure, it is possible for the aligned collimator layers to be bonded to each other in such a way that the glued collimator layers of the collimator module with absorber walls arranged in a grid form. In this case, the collimator layers in a particularly simple and yet precise manner to be aligned with one another. This corresponds to the actual grid form a predetermined grid form a particularly precise.
