Claim 10:
11. A method of grouping detection events in an imaging apparatus, comprising:
grouping a second event of gamma rays detected at detector crystals in a first cell of parameterized cells included in a demultiplexer same as a first event of the gamma rays, wherein the parameterized cells are connected back to back and form a circular operating chain, when the second event satisfies both of (1) a time window determined by the first event, and (2) a first zone assignment determined by a location of detection for the first event; and
grouping the second event in a second cell of the parameterized cells, different from the first cell, when the second event does not satisfy at least one of the time window and the first zone assignment.
