Abstract

The disclosure relates to a device and positron emission tomography (PET) scanner for acquiring a PET image and a system for generating the PET image. The disclosure describes a device that may have one or more moveable portions. The device may comprise an upper portion and a lower portion. The upper portion and lower portion define a cavity for a patient. At least one of the upper portion or the lower portion may be movable. The upper and lower portions may comprise a cap and wings, respectively, At least one of the caps and/or wings may comprise one or more detection modules. The wings may also move with respect to a corresponding cap.

Dependent claims

A device comprising:

an upper portion comprising:
an upper first wing;
an upper cap operably connected to the upper first wing;
and
an upper second wing operably connected to the upper cap;
a lower portion comprising:
a lower first wing;
a lower cap operably connected to the lower first wing;
and
a lower second wing operably connected to the lower cap, wherein
the upper portion and lower portion define a cavity, wherein at least one of the upper portion or lower portion is moveable to change a distance between the upper portion and the lower portion, and wherein at least one of the upper first wing, the upper cap, the upper second wing, the lower first wing, the lower cap, and the lower second wing comprises one or more detection modules,
wherein the one or more detection modules comprise:
a scintillator array comprising a plurality of scintillator crystals;
a plurality of detectors provided on a first end of the scintillator array;
and
a plurality of prismatoids provided on a second end of the scintillator array, wherein each prismatoid of the plurality of prismatoids is configured to redirect particles between second ends of scintillator crystals of the scintillator array,
wherein first ends of a first group of scintillator crystals of the scintillator array are configured to direct particles to a first detector of the plurality of detectors, and
wherein first ends of a second group of scintillator crystals of the scintillator array are configured to direct particles to a second detector substantially adjacent to the first detector, wherein the plurality of prismatoids is oriented towards the cavity.
