Abstract

A method for manufacturing a collimator module and/or a collimator bridge is disclosed, as well as a collimator module, a collimator bridge, a collimator and a tomography device. A collimator module for a radiation detector includes a plurality of collimator layers. These collimator layers each have a flat lattice structure. In an embodiment, a first collimator layer has a holder structure and the collimator layers are aligned relative to one another by the holder structure on a first holder tool. With such a holder structure it is possible to glue the aligned collimator layers to one another such that the glued collimator layers form the collimator module with absorber walls disposed in a lattice shape. In such cases, the collimator layers can be aligned to one another in an especially simple and yet precise manner. Through this the actual lattice shape corresponds especially accurately to a prespecified lattice shape.
