METHOD FOR DETERMINING DISPOSITION OF DETECTOR MODULE, GAMMA-RAY DETECTOR, AND PET DEVICE

摘要

The present invention increases the uniformity of PET device performance. The present invention pertains to a method that is for determining the disposition in a gamma-ray detector of a plurality of detector modules configured in a manner so as to convert, to an electrical signal, the light arising in response to incoming gamma rays arising from a pair-annihilation event. First, the performance information of each of the plurality of detector modules is acquired. Next, on the basis of the acquired performance information, the relative positions of each of the plurality of detector modules in the gamma-ray detector are determined.
