Abstract

When constructing a nuclear detector module in a gantry, a plurality of overlapping light guide modules () are mounted to the gantry in a spaced-apart fashion, and a plurality of underlapping light guide modules () are mounted in between each pair of overlapping light guide modules (). Each of the underlapping modules and the overlapping modules includes a scintillation crystal array () on an interior surface thereof, and a plurality of PMTs on an exterior surface thereof. Overlapping modules () have overlapping structures () that interface with underlapping structures () on the underlapping modules () and thereby eliminate a seam directly beneath PMTs that overlap the crystal arrays of both an overlapping module and an underlapping module. Optical grease is used to form a resilient grease coupling and reduce light scatter between the underlapping and overlapping modules.
