RADIATION DETECTOR WITH COUNTING ELECTRONICS |
摘要 |
The invention relates to a radiation detector, particularly an X-ray detector (100), comprising a counting circuitry (10, 20, 30) for counting electrical pulses generated by the (sub-)pixels (2) of the detector. In the counting circuitry, the results counted by a fast counting stage (10) are at intervals transferred to a slow counting stage (20). The fast counting stage (10) may for example comprise a fast counter (111) with a low bit-depth operating as a frequency divider in front of a slow counter (121) of high bit-depth in the slow counting stage (20). The counting circuitry (10, 20, 30) can optionally be fed via a multiplexer (4) with the signals of several (sub-)pixels (2). Furthermore, the pixels (1, 2) of the radiation device may optionally deliver energy resolved pulses. |
