Abstract:
1. A radiation detector for measuring one or more characteristics of a radiation, comprising an array of detector pixels, a clock pulse generator, the array of detector pixels comprising at least a first detector pixel and a second detector pixel, the first detector pixel and the second detector pixel separately comprising: a sensor producing an electrical signal in response to an event of a photon or charged particle of said radiation impinging on said sensor; pixel electronics configured to receive and process said electrical signal, the pixel electronics comprising: wherein the predefined ranges of the individual event counters of the first detector pixel differ at least in part from the predefined ranges of the individual event counters of the second detector pixel; wherein the radiation detector further comprises a copy unit, said copy unit comprising means for receiving a TOT-count value, a set of output ports copying said TOT-count value, a set of comparing units, each comparing unit comprising a set of TOT-count limit values, defining a set of TOT-count ranges, and being associated with an event counter, and comprising means for detecting when a measured TOT-count is within or above a range, and means for incrementing an event counter when a measured TOT-count is within or above said associated range.
