Abstract
A scattered-radiation collimator is disclosed for radiological radiation with a multiplicity of absorber elements that are arranged one behind the other in a collimation direction and held in a support frame. In at least one embodiment, the support frame includes a holding device for holding the absorber elements on opposite sides across the collimation direction, and at least one strip-like holding element spans the absorber elements in a collimation direction on the radiation entry side and/or the radiation exit side of the scattered-radiation collimator and additionally fixes the absorber elements on the longitudinal edges thereof in a mechanical fashion. In at least one embodiment, the holding elements prevent deformations of long absorber elements caused by centrifugal forces to a large extent. This affords the possibility of implementing scattered-radiation collimators with a large Z-coverage that meet the demand on the absorber elements in respect of dimensional stability and positional accuracy. Moreover, at least one embodiment of the invention relates to a method for producing such a scattered-radiation collimator.
