1. An X-ray imager comprising:
an X-ray source;
a semiconductor detector; and
a processor,
wherein on a rear side of the semiconductor detector facing away from a front side, in each of a plurality of imaging regions of the semiconductor detector, at least one imaging electrode is arranged and a plurality of imaging detectors each contact at least one of the imaging electrodes to acquire first measurement values relating to X-ray signals of the imaging electrodes,
wherein the processor is configured to establish an image dataset dependent upon the first measurement values,
wherein at least one additional electrode is arranged on the rear side of the semiconductor detector outside the imaging regions, at least one current sensor contacts the at least one additional electrode to acquire current flow by way of second measurement values relating to the at least one additional electrode,
wherein the imaging electrodes and the at least one additional electrode are each connected by way of at least one respective contact to a respective connecting electrode of an integrated circuit which implements the imaging detector, and
wherein the at least one additional electrode is connected, via at least two contacts spaced apart from one another, to one or each to one of the connecting electrodes of the integrated circuit.
