Abstract

A method and a detector system are disclosed for the photon-counting detection of x-ray radiation with direct conversion detectors. In at least one embodiment of the method, as a function of the existing radiation energy, current and/or voltage pulses which are largely proportional thereto are generated, and the generated current and voltage pulses are counted in the detector when a predetermined current and/or voltage source is exceeded, whereby a threshold is used as a predetermined current and/or voltage threshold, which corresponds to a detection of a photon with an energy which is less than the k-edge of the detector material used.
