    摘要： A method and a circuit arrangement are disclosed for determining radiation intensity using counting detectors or detector elements, in which x-ray radiation photons, which are either absorbed or absorbed in part, generate electrical signals, the pulse number and pulse height of which is correlated to an incident radiation intensity, and the radiation intensity is at least determined by counting the pulses. According to at least one embodiment of the invention, the signal pulses incident on at least one detector or detector element are detected simultaneously by at least one continuously operating pulse height discriminator and by at least one pulse height discriminator operating in a clocked fashion, with the number of incident signal pulses being determined with the aid of these two items of detection information.

    摘要： A quantum detector module for the quantitative and energy-resolved determination of quantum absorption events, a quantum detector, a method for determining quantum absorption events, a computer program product and a radiation detection device are disclosed. In at least one embodiment, the quantum detector module includes a multiplicity of detector pixels. In order to determine the quantum absorption events particularly precisely, in at least one embodiment it is provided that the detector pixels have at least two mutually different pixel apertures.
