Abstract: 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.

Abstract: A detector unit of a computer tomograph includes a base surface that faces a support ring of a gantry of the computer tomograph in a mounting position, and a detector surface that is angled away from the base surface in an approximately perpendicular fashion, faces an isocentric axis of the gantry in the mounting position, and along which there are fitted a number of detector elements for detecting x-radiation. The base surface has an air inlet fitted in such a way that a cooling airflow applied from outside to the base surface is guided onto the inner side of the detector surface. In the mounting position, the air inlet corresponds with an air channel guided in the support ring or between the rotary carriage and the support ring.

Abstract: A collimator for a computer tomograph includes a number of collimator plates and a holder for the collimator plates. The collimator plates include, at the edge, a number of tabs spaced apart from one another. In a fashion corresponding to this, the holder has receptacles that are assigned to the tabs and that are spaced apart from one another, into which the tabs of the collimator plates engage. This configuration ensures highly accurate positioning of even long collimator plates.

Abstract: A detector unit of a computer tomograph is disclosed that is simple with regard to implementation, effective and, in particular, rotationally stable. The detector unit includes a base surface that faces a support ring of a gantry of the computer tomograph in a mounting position, and a detector surface that is angled away from the base surface in an approximately perpendicular fashion, faces an isocentric axis of the gantry in the mounting position, and along which there are fitted a number of detector elements for detecting x-radiation.

In the mounting position, the air inlet corresponds with an air channel guided in the support ring or between the rotary carriage and the support ring.
