Abstract
The present invention relates to an x-ray detector comprising a sensor unit for detecting incident x-ray radiation comprising a number of sensor elements, a counting channel per sensor element for obtaining a count signal by counting photons or charge pulses generated in response to the incident x-ray radiation since a beginning of a measurement interval, an integrating channel per sensor element for obtaining an integration signal representing the total energy of radiation detected since the beginning of the measurement interval, and a processing unit for estimating, from the integration signals of the sensor elements, count signals of sensor elements whose counting channel has been saturated during the measurement interval.
