Abstract
An X-ray detector is disclosed for detecting individual quanta. In at least one embodiment, the X-ray detector includes a plurality of detector elements and an evaluation unit that is connected to the latter for data purposes and is set up in such a way that each detector element is assigned a first energy threshold, wherein in each case one portion of various radiation spectra that can be picked up by the detector element exhibits an energy below the energy threshold, and a further portion of the respective radiation spectrum exhibits an energy above the energy threshold. Further, the energy thresholds of the various detector elements are set in a different fashion in such a way that the ratio between the portion, exhibiting an energy above or below the energy threshold in the case of a first radiation spectrum, of the radiation spectrum and the portion, exhibiting an energy above or below the energy threshold in the case of a second radiation spectrum, of the radiation spectrum is intermatched in the case of the various detector elements.
