Photon-counting x-ray detector, method for operation of a photon-counting x-ray detector and x-ray device

A photon-counting x-ray detector, comprising:

• a number of pixel elements;
• a converter element for conversion of x-ray radiation into electrical signals;
• a first signal processing stage for each respective pixel element of the number of pixel elements, the first signal processing stage including at least one comparator and at least one monoflop unit, wherein
• the at least one comparator is configured to compare an electrical signal from a pixel element with a signal threshold value, and provide a digital pixel signal to the at least one monoflop unit based on the comparison,
• the at least one monoflop unit is configured to, based on the digital pixel signal, provide a pulse signal with a defined pulse length to an output of the first signal processing stage;
• a second signal processing stage for each respective pixel element of the number of pixel elements, the second signal processing stage including at least one delay unit and at least one counting element, wherein
• each respective output of the first signal processing stage is coupled to a respective delay unit for signaling purposes,
• each delay unit is configured to provide a pulse signal with a respective adjusted delay, as a respective adjusted pulse signal, to a respective counting element,
• wherein the respective adjusted delay is based on a circuit-related delay of a respective pixel element of the number of pixel elements, and
• each counting element is configured to count a counting signal based on the respective adjusted pulse signal.
