Abstract

A detector is disclosed, in particular for X-radiation. The detector includes an array of photodiodes, each respectively corresponding to a pixel with regard to size of their photosensitive receiving surface. Each photodiode is subdivided in the same way into at least two sub-photodiodes. Further, each photodiode includes at least one electric switch such that only one or all the sub-photodiodes of the photodiode are connectable to an evaluation circuit.
