We have developed a three-dimensional (3-D) position-sensitive radiation detector named X’tal cube, which can be applied to a PET detector. The X’tal cube is composed of a scintillation crystal block and multi-pixel photon counters (MPPCs). The crystal block is segmented three-dimensionally into small cubes by optical discontinuity (3-D segmentation) and no reflector is inserted inside. Scintillation...
X'tal cube is the 3D position-sensitive radiation detector we have developed. Its structure uses multi-pixel photon counters (MPPCs) that are coupled on all sides of the scintillation crystal block which is segmented into a 3D array of cubes. No reflector is inserted into the crystal block so that scintillation light originating in one of the cubic segment spreads 3-dimensionally and distributes among...
