PIXELLATED SCINTILLATOR READOUT ARRANGEMENT AND METHOD

摘要

A pixellated scintillator readout arrangement is presented, the arrangement comprising a plurality of scintillator pixels arranged in a scintillator array, and a plurality of photodetectors arranged to receive light from, or address, the scintillator pixels. The photodetectors may be arranged on both a first side and a second side of the scintillator array. Each photodetector may be arranged to leave a gap adjacent to the scintillator pixel which is addressed by that photodetector. Non-photosensitive elements such as tracking and bondpads may be arranged in at least some of the gaps. Electronic components such as electronic amplifiers may be arranged in at least some of the gaps. The photodetectors may be arranged in linear arrays addressing alternate lines of scintillator pixels on either side of the scintillator array. Each photodetector may be arranged to address a single pixel (as illustrated) or more than one pixel (not shown).
