Abstract: An imaging apparatus includes a first imaging modality (1021), a second imaging modality (1022), wherein the first and second imaging modalities are in alignment with scanning zones for scanning an object or subject, and a third imaging modality (102N) which is selectively moveable between a first location (114) in which the third imaging modality is in alignment with the scanning zones for scanning the object or subject and a second location (122) in which the third imaging modality is outside of alignment with the scanning zones.

Abstract: A multi-modal imaging system (1) includes a fixed gantry (2), and a swivel gantry (8). The fixed gantry (2) supports a first imaging modality. The swivel gantry (8) connects to the fixed gantry (2) by at least three mounting points (10) and supports a second imaging modality. Selectively the swivel gantry (8) includes a swivel frame (16) and at least three mounting points (10) for mounting the fixed and swivel gantries together in an imaging configuration. The at least three mounting points (10) include at least one hinge (14) which permits the swivel gantry to swivel about the fixed gantry into a service configuration.

Abstract: When constructing a nuclear detector module in a gantry, a plurality of overlapping light guide modules (10) are mounted to the gantry in a spaced-apart fashion, and a plurality of underlapping light guide modules (12) are mounted in between each pair of overlapping light guide modules (10). Each of the underlapping modules and the overlapping modules includes a scintillation crystal array (16) on an interior surface thereof, and a plurality of PMTs on an exterior surface thereof. Overlapping modules (10) have overlapping structures (22) that interface with underlapping structures (18) on the underlapping modules (12) 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.
