    摘要: Radiation detector (1) for measuring one or more characteristics of a radiation, comprising one or more detector pixels (3), a clock pulse generator, each detector pixel (3) comprising a sensor (20) producing an electrical signal in response to an event of a photon or charged particle of said radiation impinging on said sensor (20); a pixel electronics (24) adapted for receiving and processing said electrical signal, comprising an analog processing unit (62) for amplifying and shaping said electrical signal and producing a shaped pulse said pixel electronics (24) comprises time determination unit (51) for counting the TOT-count, the TOT-count being the number of clock pulses occurring during the time interval when said shaped pulse is above a threshold. Said pixel electronics comprises a plurality of event counters (82), each event counter (82) counting the number of events having a TOT-count in a predefined ranges.
