    摘要: An X-ray detector includes a directly converting semiconductor layer for converting an incident radiation into electrical signals with a band gap energy characteristic of the semiconductor layer, and at least one light source for coupling light into the semiconductor layer, wherein the generated light, for the simulation of incident X-ray quanta, has an energy above the band gap energy of the semiconductor layer. In at least one embodiment, it includes at least one evaluation unit for calculating an evaluation signal from the electrical signals generated when the light is coupled into the semiconductor layer, and at least one calibration unit for calibrating at least one pulse discriminator on the basis of the evaluation signal. This provides the prerequisites for a rapidly repeatable calibration of the X-ray detector taking account of the present polarization state without using X-ray radiation. At least one embodiment of the invention additionally relates to a calibration method for such an X-ray 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 protective layer is provided for an image detector used for an x-ray image. This image detector comprises a layer of luminescent material that is to be protected against mechanical stress and moisture. A polymeric protective layer is disposed thereupon and is hardened exclusively in an area which does not border the layer of luminescent material. The hardened area provides protection against mechanical stress while the remaining area forms a moisture barrier. An appertaining method is provided for producing a polymeric protective layer on an image detector for an x-ray image, which is provided with a layer of luminescent material. The protective layer is deposited on the layer of luminescent material and then is hardened only in an area which does not border the layer of luminescent material.
