Abstract
Disclosed is a photon-counting x-ray detector system having a plurality of photon-counting channels, and at least one anti-coincidence circuit, each of which is connected to least two of the channels and configured to detect coincident events in the connected channels. The x-ray detector system further includes an anti-coincidence controller configured to control the operation of the at least one anti-coincidence circuit based on photon count information by gradually adapting the operation of the at least one anti-coincidence circuit with increasing count rates, starting from a threshold count rate.
