Claim 0:
1. A detector arrangement comprising a pair of spaced apart detector arrays oriented generally parallel to each other, wherein the detectors are configured to detect photons emitted from an object, wherein each detector in one of the arrays is linked to or associated with one or more other detector in the other one of the arrays to define a region of interest (RoI), each RoI including a subset of the detectors in the pair of arrays, and wherein the detector arrangement comprises or is communicatively coupled to a coincidence trigger unit which 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.
