Abstract

[PROBLEMS TO BE SOLVED] A TOF-PET is provided for making it possible to obtain exact time information. [MEANS FOR SOLVING THE PROBLEMS] The selection of photomultiplier tubes with rising-up time dispersion is carried out to dispose them in a ring like arrangement so that a rising-up difference is minimized. With that disposition, even when light from a scintillator is incident on a plurality of photomultiplier tubes, rising-up time ∑ tr of the total signal output is not dispersed, so that correction is possible at actual measurement if a rising-up time difference Δ ε between radiation detectors is given in advance as correction data. According to the method set forth above, it is possible to provide a TOF-PET that can obtain exact time information.
