We are investigating the influences of heavy ion irradiation on the detectors for in-beam OpenPET by using the Heavy Ion Medical Accelerator in Chiba (HIMAC) at the National institute of Radiological Sciences (NIRS). "OpenPET" which consists of two detector rings separated axially is suitable for in-beam PET in heavy ion therapy due to the open space between the separated detector rings...
We have proposed a depth of interaction (DOI) PET detector named X'tal cube, in which a number of Multi-Pixel Photon Counters (MPPCs) are coupled on various positions of six surfaces of a segmented scintillation crystal block. There are no reflectors within the block, and the areas among MPPCs on the surface are covered with reflector. The MPPC is thin and light solid-state photo-detector so that...
