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.
