Claim 6:
7. A detection system which comprises:
a detector arrangement comprising at least one array of detectors, wherein the detectors are configured to detect photons emitted from an object, wherein each detector in the array is linked to or associated with one or more other detector in the array to define a region of interest (RoI), each RoI including a subset of the detectors in the array;
a coincidence trigger unit forming part of or communicatively coupled to the detector arrangement, wherein the coincidence trigger unit is configured to register or determine a coincidence in response to receiving detection signals from two different detectors forming part of the same RoI and indicating detection of substantially back-to-back co-linear and co-incident photons in the RoI; and
a plurality of data acquisition (DAQ) computers configured to receive event data from the detector arrangement, wherein the event data is related to a coincidence registered or determined by the coincidence trigger unit, wherein each DAQ computer is configured to receive event data only from detectors which form part of one or more RoIs which are associated with the particular DAQ computer.
