ABSTRACT:
A positron emission tomographic scanner is provided with cross-slice event data handling capability by adding only a coincidence detector and register in common to the circuitry for two adjacent planar detector arrays and adding an OR gate to the circuitry for each array. The improvement permits the same circuitry to be utilized for both cross-slice event processing and intra-slice event processing. Selection of the identification code for a detector is determined by a first coincidence detector in the case of an intra-slice event and the added coincidence detector in the case of an inter-slice event.
