 note = {We previously reported on a new PET detector with 3 mm isotropic spatial resolution obtained using the X'tal cube structure. The X'tal cube is composed of a segmented crystal block and multi-pixel photon counters (MPPCs), and it detects scintillation photons in three dimensions (3D) by arranging MPPCs on multiple surfaces of the crystal block. With this structure and photo-detection method, we thought it would be possible to collect scintillation photons efficiently enough to get high spatial resolution.
   In this study, we achieved 1 mm isotropic spatial resolution. The developed X'tal cube detector was composed of 96 MPPCs with 3.0 mm x 3.0 mm sensitive area and 1.0 x 1.0 x 1.0 mm3 LYSO crystals, which were structured into 16 x 16 x 16 arrays. We evaluated crystal identification and energy performance, and the results showed that the X'tal cube has the expected 1 mm isotropic spatial resolution., 2010 Nuclear Science Symposium and Medical Imaging Conference},
