Abstract
The disclosure is directed to a device that includes a cavity formed by a plurality of rails, the plurality of rails connected to both a first support and a second support, each at predetermined intervals about a circumference of the first support and the second support; and at least one particle detection device operably connected to each rail of the plurality of rails. The disclosure is also directed to a scanner that includes the device, and a processor.
Claims19
A device, the device comprising:
- a first support;
- a second support spaced from the first support in an axial direction;
- a plurality of rails each respectively connected to an exterior-facing side of the first support and an exterior-facing side of the second support, the plurality of rails extending between the first support and the second support where at least a part of the plurality of rails is orthogonal to the first support and the second support, the plurality of rails, the first support and the second support defining a cavity, the exterior-facing side of the first support and the exterior-facing side of the second support being a side opposite to a side of the first support and a side of the second support facing the cavity, the rails being disposed at predetermined intervals about a circumference of the first support and the second support;
- and
- a plurality of particle detection devices operably connected to each rail of the plurality of rails in a row of particle detection devices, where a respective rail overlaps at least part of the row of particle detection devices in a radial direction, each particle detection device comprising:
- a scintillator array comprising a plurality of scintillator crystals;
- a plurality of detectors provided on a bottom end of the scintillator array;
- and
- a plurality of prismatoids provided on a top end of the scintillator array, wherein each prismatoid of the plurality of prismatoids is configured to redirect particles between top ends of scintillator crystals of the scintillator array,
- wherein bottom 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 bottom 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 of each particle detection device is oriented towards the cavity.
