A shadow mask and method for adjustment are disclosed. The shadow mask may be for an X-ray detector including detector elements, which may further be provided for a computed tomography unit, for example. The shadow mask has a mask plate with holes of which each is assigned a detector element. At least one adjusting hole of the mask plate includes enlarged dimensions in such a way that it is adapted to the dimensions of at least two detector elements. The adjusting hole serves for the method of adjusting the shadow mask over the X-ray detector. Measurement signals of the detector elements that are assigned to the at least one adjusting hole, are determined by using X-radiation. The shadow mask and the X-ray detector are adjusted relative to one another on the basis of a comparison of the measurement signals of the detector elements. |
