摘要：PROBLEM TO BE SOLVED: To provide a nuclear medicine diagnostic device with its sensitivity enhanced by reducing data counting miss. SOLUTION: An FPGA 31 of a detector unit 2 has a first data sort part 51 and a first scattered-ray processing part 53. With packet data from within the detector unit 2 sorted in order of detection time in the sort part 51, scattered-ray processing is performed in the processing part 53. A plurality of detector units 2 are turned into a block to collect packet data to a data collection unit 3. The collection unit 3 has a second data sort part 57 and a second scattered-ray processing part 59. Packet data from FPGAs 31 of a plurality of detector units 2 are sorted in order of detection time in a second data sort part 57 while scattered ray processing is performed in the processing part 59. The packet data coming out of the processing part 59 are transmitted to a data processor 12 where a simultaneous counting processing is performed. COPYRIGHT: (C)2008,JPO&INPIT
