1. A PET detector system comprising:
- a first detector subsystem comprising a first plurality of detector modules configured in a ring, the first subsystem of detector modules adapted to generate first output characterizing radiation incident thereon;
a second detector subsystem comprising a second plurality of detector modules, the second subsystem of detector modules adapted to generate second output characterizing radiation incident thereon; and
imaging electronics configured to convert the first and second output into PET images of first and second regions of a body, respectively;
wherein each of the detector subsystems comprises a first layer of scintillator elements extending in a first direction, a second layer of scintillator elements extending in a second direction, and an intermediate layer defined between the first and second layers, the intermediate layer configured to modulate light sharing between the first layer of scintillator elements and the second layer of scintillator elements.

Abstract
Detector module designs for radiographic imaging include first and second layers of scintillator rods or pixel arrays oriented in first and second directions. The first and second directions are transversely oriented to define a light sharing region between the first and second layers. Encoding features may be disposed in, on or between the first and second layers, and configured to modulate propagation of optical signals therealong or therebetween.
