Abstract
A method, a circuit arrangement and an X-ray system, in particular a CT system, are disclosed wherein, in order to correct the count rate drift of a detector for ionizing radiation having quantum-counting detector elements which include a combination of at least two counters with significantly different energy thresholds, and on the basis of previously determined functional dependencies of count rates on one another and using at least one of the counters per detector element as the reference, the count rates of the respective other counters with different energy thresholds are corrected.
