摘要： In a method, with a current measurement, the history of the radiation exposure of the X-ray detector is taken into account with respect to the overall X-ray detector or subareas of the X-ray detector, in respect of a reduction in the measurement sensitivity produced as a result and a recovery of the reduction in the measurement sensitivity, and the determined measuring signal is corrected with a correction factor which is dependent on the history of the radiation exposure. Furthermore, an X-ray recording system includes a detector which includes a plurality of detector elements, which are read out in groups channel by channel and a read-out apparatus with computer-assisted device for correcting read-out detector data prior to a further processing of the detector data to form projective or tomographic images.

摘要： An x-ray detector includes a large number of pixels, each of the latter being configured from one or more sub-pixels. Each of the sub-pixels include a detector material for the direct conversion of incident X-ray radiation into an electric signal. A device for converting the electric signals into corresponding digital signals is associated with each of the sub-pixels and the detector is also equipped with a device for processing said digital signals into a combined digital signal representing the number and/or energy of the X-ray quanta that are incident on the pixel.

摘要： A computed tomography (CT) device has adjustable operational parameters and a control unit and a unit for preselecting a combination of operational parameters for an examination to be carried out. The control unit determines, for the case where a combination of operational parameters which might lead to an impermissible operating state is preselected for an examination to be carried out, a value for at least one operational parameter which deviates from the preselected combination of operational parameters and for which the planned examination can be carried out in a manner avoiding the impermissible operating state without a significant reduction in the image quality by comparison with the preselected combination of operational parameters.

摘要： An X-ray detector is for a CT device and includes a phosphor layer for generating electromagnetic radiation as a function of the occurrence of X-radiation, and a photodetector layer for detecting the electromagnetic radiation generated by the phosphor layer. The phosphor layer includes ceramic material and the photodetector layer includes organic material. A process is further for producing an X-ray detector, including the steps of producing a phosphor layer from a ceramic material and applying a photodetector layer made from an organic material to the phosphor layer via a spinning, printing or beam/jet process or by sticking it on as a film. It is optionally possible to provide a further process step for polishing the surface of the phosphor layer before applying the photodetector layer.

摘要： A method is proposed for producing an anti-scatter grid or collimator for a radiation type, which is formed from at least one base body of prescribable geometry having transmission channels or slits for primary radiation of the radiation type which extend between two opposite surfaces of the base body. The base body is formed from a structural material that strongly absorbs the radiation type, either using the injection molding technique or by way of the technique of stereolithography. The method can be used to produce an anti-scatter grid or collimator with high accuracy and with the aid of only a few steps.
