POSITRON RADIATION TOMOGRAPHY (PET) DETECTOR MODULE, POSITRON RADIATION TOMOGRAPHY (PET) SCANNER SYSTEM, OPTICAL FIBER PLATE, AND NUCLEAR MEDICINE IMAGE PHOTOGRAPHY DETECTOR MODULE

摘要

PROBLEM TO BE SOLVED: To improve precision of gamma-ray detection.SOLUTION: A PET detector module 200 includes an array type scintillation crystal element 203, a plurality of photosensors 201, and an optical fiber plate 202. The plurality of photosensors 201 are arranged to cover the array type scintillation crystal element 203, and configured to receive light emitted from the array type scintillation crystal element 203. The optical fiber plate 202 is arranged between the array type scintillation crystal element 203 and the plurality of photosensors 201, and configured to guide light emitted from scintillation crystal up to the plurality of photosensors 201.
