High resolution depth-encoding pet detector with prismatoid light guide array

A particle detector, comprising:

• a scintillator array comprising a plurality of scintillator crystals;
• a plurality of detectors provided on a first end of the scintillator array, where there are multiple scintillator crystals per detector;
• a plurality of prismatoids provided on a second end of the scintillator array, where the prismatoids are offset with the detectors such that at least two prismatoids overlap the same detector;
• and
• at least one processor in operative communication with the plurality of detectors,
• wherein the at least one processor comprises a plurality of supervised machine learning algorithms configured to perform three dimensional (3D) gamma ray localization of at least one interaction site within at least one scintillator crystal of the plurality of scintillator crystals.

A particle detection device, comprising:

• a scintillator array comprising a plurality of scintillator crystals;
• a plurality of detectors provided on a first end of the scintillator array where there are multiple scintillator crystals per detector;
• and
• a plurality of prismatoids provided on a second end of the scintillator array where the prismatoids have a different shape depending on a location of the prismatoid with respect to the plurality of detectors, and where each prismatoid is in contact with scintillator crystals in contact with at least two different detectors, the at least two different detectors being adjacent detectors, wherein each prismatoid is configured to redirect particles between scintillator crystals in contact with the respective prismatoid.
