Abstract

The application describes an X-ray detector for use in a medical equipment, wherein the detector comprises an unit for transforming X-ray radiation into electrical charge, a first capacitor for being charged by an electrical charge, wherein the first capacitor is electrically connected to the unit for transforming, a second capacitor for being charged by an electrical charge, and a first gain switching gate, wherein the second capacitor is electrically connected with the unit for transforming if the first gain switching gate is in on-state, wherein the detector is adapted to switch on the first gain switching gate for short periods. Further the application describes an X-ray system comprising a detector according to the invention, wherein the system is adapted for gain selection, wherein the detector is adapted to switch on the first gain switching gate for short periods. Further, the application describes a method for using a detector according to the inventive concept, wherein the first gain switching gate is switched on only for short periods of time for redistribution of electrical charge between the first capacitor and the second capacitor.
