Abstract
An evaluation circuit for an x-ray detector for signaling coupling to a converter, designed to convert incident x-radiation into electrical signals. In at least one embodiment, the evaluation circuit includes a multiplicity of pixel-electronics modules. A respective pixel-electronics module is designed to process electrical signals fed into the respective pixel-electronics module from the converter, order to produce a respective digital pixel-measurement signal. Further, each of the respective pixel-electronics modules has at least one respective settable digital signal-processor, designed to adapt a respective processed digital pixel-measurement signal in a respective pixel-electronics module.
