| 摘要 |
The present invention relates to an x-ray detector comprising a sensor unit (200, 300) for detecting incident x-ray radiation comprising a number of sensor elements (230, 311-314 ), a counting channel (240) 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 (250) 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 (260) for estimating, from the integration signals of the sensor elements (321), count signals of sensor elements (311, 312) whose counting channel has been saturated during the measurement interval. |
