Abstract:
1. An X-ray detector, comprising: a unit configured to transform X-ray radiation into electrical charge; a first capacitor configured to be charged by electrical charge generated by the unit, wherein the first capacitor is electrically connected to the unit; a second capacitor configured to be charged by the electrical charge generated by the unit, wherein the second capacitor is connected to the unit; and a first gain switching gate, wherein the second capacitor is electrically connected with the unit if the first gain switching gate is in an on-state, and wherein during a first exposure window of the unit, the first gain switching gate is switched on for a continuously long period of time compared to a second exposure window of the unit, immediately following the first exposure window, such that during the second exposure window, the first gain switching gate is switched on in multiple discrete and discontinuous short periods of time in an on and off sequence during the second exposure window.
