  • Publication number: 20120025091
    Abstract: A method of coincidence detection and a tomography system using the same are provided. In the method and system, by combining original trigger signals and time mark information, at a time point of a rising edge of a system main clock, a combination of the trigger signals of a plurality of radiation detectors of the system is obtained, and a type of the combination of the trigger signals is determined according to a predetermined event relation. If the combination of the trigger signals belongs to an effective event, a time mark procedure is utilised for judging the trigger signals in the event, in which it is determined whether a difference between two time mark information respectively associated with the trigger signals of the two corresponding radiation detectors is within a coincidence time window or not, thereby judging whether the effective event is an annihilation event.
