    摘要： A collimator is disclosed for a radiation detector including at least three spacing elements arranged on a radiation exit face of the collimator. In at least one embodiment, they are embodied so as to mount the collimator in a stable manner with respect to a radiation converter of the radiation detector. The at least three spacing elements enable a very precise and stable alignment of the collimator in respect of the radiation converter despite manufacturing-related curves or unevennesses in the radiation exit face and/or the mounting surface on the part of the radiation converter. At least one embodiment of the invention also relates to a manufacturing method for such a collimator, as well as a method for manufacturing a radiation detector.

    摘要： A detector module is disclosed including a plurality of directly converting detector submodules, each with a back contact, and a scattered radiation collimator spanning the detector submodules. For contacting the back contacts, a contacting unit is provided in at least one embodiment and designed so that a contact connection is established between the contacting unit and the counter-electrodes by way of assembly-related proximity of the scattered radiation collimator and the counter-electrodes.

    摘要： 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.

    摘要： A detector is disclosed, in particular for X-radiation. The detector includes an array of photodiodes, each respectively corresponding to a pixel with regard to size of their photosensitive receiving surface. Each photodiode is subdivided in the same way into at least two sub-photodiodes. Further, each photodiode includes at least one electric switch such that only one or all the sub-photodiodes of the photodiode are connectable to an evaluation circuit.
