Claim:
1. A counting digital x-ray detector for recording x-ray images of an object irradiated by x-ray radiation, the counting digital x-ray detector comprising: an x-ray converter for converting x-ray radiation into an electric signal; and a matrix with a plurality of counting pixel elements, wherein each counting pixel element of at least a portion of counting pixel elements of the plurality of counting pixel elements has a signal input and two circuits for converting the electrical signal into a count signal, wherein a first circuit of the two circuits is configured to convert a signal entering a respective pixel element of the plurality of counting pixel elements directly into a count signal and to count the count signal, and the second circuit is configured to convert the signal entering the respective pixel element directly together with coincidently occurring signals of at least one neighboring pixel element of the plurality of counting pixel elements into a count signal and to count the count signal, and wherein the first circuit, the second circuit, or the first circuit and the second circuit are activatable individually, and the first circuit and the second circuit are activatable together.
