| 内容記述 | The X'tal cube is a PET detector we have developed. It has the new structure, which consists of a monolithic scintillation crystal block segmented 3-dimensionally into cubes and semiconductor photo-detectors are coupled on all sides of the crystal block. The crystal segment originating scintillation light can be identified by a simple position calculation with the photo-detector signals. Determination of the crystal segment provides radiation detected location inside the crystal block including depth of interaction (DOI) information which is necessary for a PET scanner to have both high sensitivity and high spatial resolution. We have already showed sufficient performance of the X'tal cube with the prototype using multi-pixel photon counters (MPPCs) for the photo-detectors and a 3-dimensional (3D) array of cubic crystals for the crystal block (array-X'tal cube). Because we newly succeeded to fabricate the 3D array by applying laser processing to a monolithic crystal for easy and reliable assembly, in this study, we evaluated performance of the X'tal cube using the monolithic crystal as the crystal block (laser-X'tal cube). The results showed high crystal identification performance and average energy resolution of 8.6 % for all crystal segments, which are superior to the array-X'tal cube performance. | |||||
