METHOD FOR ACTIVATING AN X-RAY DETECTOR AND ASSOCIATED CONTROL UNIT

摘要

In a method and control unit for activating an X-ray detector, having an X-ray sensitive sensor layer and an arrangement of pixel electrodes connected at the back to the sensor layer, an individually adjusted depletion voltage is applied to each of the pixel electrodes. The value of the depletion voltages applied to different pixel electrodes is chosen to be different such that the effective pixel sizes respectively associated with the pixel electrodes are aligned with each other.

1. A method for activating an X-ray detector comprising an X-ray sensitive sensor layer having a front side on which X-ray radiation is incident and having a back side to which an arrangement of pixel electrodes is connected, each of said pixel electrodes having an effective pixel size, said method comprising:
applying an individual depletion voltage to each of said pixel electrodes; and individually adjusting the respective depletion voltages applied to the respective pixel electrodes, with respective values of respective depletion voltages applied respectively to different pixel electrodes being selected to have a difference therebetween that aligns the respective effective pixel sizes of the different pixel electrodes with each other.
