Panel Radiation Detector

A method for processing a detection signal of a panel radiation detector for detecting radiation event(s) of ionizing radiation, the panel radiation detector comprising:

• a plurality of adjoining plastic scintillator slab,
• a plurality of silicon photomultiplier sensors arranged at an edge of at least one of the plastic scintillator slabs, and
• a plurality of signal processing units, each of the plurality of signal processing units being connected to one of the plurality of silicon photomultiplier sensors and each comprising a digitization circuit,
• wherein the method comprises:
• detecting scintillation light generated in the scintillator slab(s) by the silicon photomultiplier sensors;
• generating a detection signal by at least one of the silicon photomultiplier sensors in response to the detected scintillation light;
• and
• generating a digitized signal for signal analysis by executing 1-bit digitization of the detection signal by the digitization circuit for determining an energy of the detected radiation event(s).
