Abstract
A photon-counting X-ray detector includes a converter element constructed to convert incident X-rays into electrical signals in dependence on a deposition of energy in the converter element, and an evaluation device. The evaluation device includes a pulse-generator to generate and output an electrical pulse based upon an electrical signal fed from the converter element; a differentiator to generate a differentiated signal of the electrical pulse output by the pulse-generator; and a first comparator to compare the generated differentiated signal with a first threshold value and, based upon the comparison, to output a binary output signal for a period for which the threshold value is exceeded.
