Abstract

We developed a Compton camera using a single 3D position-sensitive LYSO scintillator coupled multi-pixel photon counter array. The LYSO scintillators had a 4×4×4 voxelized structure and the size of each voxel was 3×3×3 mm3. On the top and the bottom of the scintillator was coupled to 4×4 channel multi-pixel photon counter arrays and the size of each counter element was 3×3 mm². The density of LYSO scintillators was 7.1 g/cm³. The emitted light from the scintillator after radiation interaction was detected by multi-pixel photon counters at the ends of a crystal block, and the depth information could be calculated based on the ratio of signals induced from the top and bottom photo counters. With this information, we can measure multiple scatterings inside the cubic scintillator and Compton imaging will be reconstructed.
