| Research Abstract |
Geiger-mode avalanche photodiodes (APDs) have many advantages to be used in PET detector, such as high internal gain, high photon detection efficiency, lower power supply and insensitivity to magnetic fields. We constructed prototype four-layer DOI detectors using two MPPC arrays and evaluated their detector performances. As a result, better detector performances as a PET detector than a detector using PS-PMT was achieved.
