Data collection device for radiation tomography apparatus and radiation tomography apparatus equipped with it, radiation tomography data collection method

摘要

PROBLEM TO BE SOLVED: To provide a data collector for radiation tomographic photographing for reducing counting loss of true coincidence counting.;SOLUTION: The data collector for a radiation tomographic photographing apparatus includes a timing circuit 27 for creating time information corresponding to a generation time of an event in which a gamma ray is detected as a pulse signal in a radiation detector, a timing synthesis part 31 for synthesizing a plurality of pieces of time information sent from a plurality of timing circuits 27 in one detection cycle into one piece of synthesized time information, and a coincidence counting discrimination part 36 for discriminating time information in true coincidence counting with reference to the plurality of pieces of synthesized time information sent from a plurality of timing synthesis parts 31.;COPYRIGHT: (C)2013,JPO&INPIT
