Abstract
A processing circuit for an X-ray sensor for collecting at least a first pixel information of a first pixel and a second pixel information of a second pixel is provided. The processing circuit comprises an amplifier (), a feedback loop () and a first collecting device (). It is provided a compensation for a non-linearity in the pixels or in the pixel circuits () by applying an inverse non-linearity () in the periphery of the X-ray sensor. A processing circuit () may provide a copy of a pixel voltage and/or of a pixel charge. In the case of pixel charge a non-linear characteristic of a pixel capacitance may be compensated.
