摘要： A radiation detector is disclosed, which in at least one embodiment includes a scintillator with septa for separating scintillator elements arranged alongside one another, and a collimator with webs for forming laterally enclosed radiation channels, wherein the webs are inserted into the septa in order to avoid crosstalk between adjacent scintillator elements. This effectively suppresses crosstalk by light or secondary quanta between adjacent pixels in conjunction with a simple construction and high mechanical stability with the consequence that the spatial resolution and quantum efficiency of the radiation detector can be increased. At least one embodiment additionally relates to a method for producing such a radiation detector.

摘要： A method is disclosed, in at least one embodiment, for producing a scintillator for a radiation detector, in which the scintillator is produced in layers by depositing a scintillator material using a PVD process. By using a PVD process, owing to lower process temperatures of less than 300° C., it is possible to produce scintillators with decay times of less than 1.1 ns over large surfaces. In this way, the prerequisites for quantitative and energy-selective detection of individual radiation quanta can be satisfied even with fluxes of more than 108 X-ray quanta/mm2*s. At least one embodiment of the invention also relates to a scintillator produced by such a method.

摘要： A radiation converter is disclosed. In at least one embodiment, the converter is for x-ray or gamma radiation and includes a multiplicity of scintillation elements which are separated from one another by separating septa. To reduce cross-talk between adjacent scintillation elements, the separating septa have a layer structure. The layer structure includes two backscatter layers, between which an absorber layer which is essentially opaque to the radiation, to scatter radiation and/or scintillation light is disposed.

摘要： A method is disclosed for energy calibrating quantum-counting x-ray detectors in an x-ray installation including at least two x-ray systems turnable around a center of rotation. A target, for producing x-ray fluorescence radiation, is positioned between the first x-ray source and first x-ray detector and irradiated with x-radiation of the first x-ray source in such a way that x-ray fluorescence radiation which strikes the second x-ray detector from the target is produced by the x-radiation of the first x-ray source. The second x-ray detector is then energy calibrated by way of the x-ray fluorescence radiation of the target. The first x-ray detector can be energy calibrated in the same way with the aid of the x-radiation of the second x-ray source. With the proposed method, the x-ray detectors of a dual-source CT x-ray installation can be calibrated with little expenditure under conditions close to those of the system.

摘要： A detector module for a radiation detector is disclosed. In at least one embodiment, the detector module includes a converter layer with contacts, arranged distributed over an area on the rear side, for transmitting electrical signals, wherein the contacts are routed, by way of rewiring, to target contacts on a target region that is smaller than this area. This provides the conditions for simple and secure signal routing between the contacts on the converter layer and readout electronics. In particular, this is successful if a substrate layer used for stabilization purposes has a cutout for the target region, through which cutout the target contacts are directly connected to the signal-routing lines of readout electronics.
