Abstract
The disclosure relates to a scintillation pixel array, a radiation sensing apparatus, a scintillation apparatus, and methods of making a scintillation pixel array wherein scintillation pixels have beveled surfaces and a reflective material around the beveled surfaces. The embodiments described herein can reduce the amount of cross-talk between adjacent scintillation pixels.
Claims20
A scintillation pixel array, comprising:
- a first and second scintillation pixel, wherein each of the first and second scintillation pixel has:
- a proximal end, and
- a distal end opposite the proximal end;
- an optical interface disposed closer to the distal end than the proximal end and including an optical coupling material extending over the distal ends of the first and second scintillation pixels;
- and
- a first mask disposed between the distal end of the first scintillation pixel and the optical interface, wherein the first mask comprises a photon absorbing material and an opening exposing at least a portion of a surface area of the distal end of the first scintillation pixel.
A scintillation pixel array comprising a plurality of scintillation pixels including a first scintillation pixel adjacent a second scintillation pixel, wherein each of the first and second scintillation pixels has:
- a proximal end,
- a distal end opposite the proximal end;
- an optical interface coupled to the distal ends of the first and second scintillation pixels;
- and
- a first mask disposed along a first side of the distal end of the first scintillation pixel, between the distal end of the first scintillation pixel and the optical interface, wherein the first mask comprises a photon absorbing material and is disposed such that less than 50% of a surface area of the distal end is covered by the first mask.
A radiation sensing apparatus, comprising:
- a scintillator array comprising a plurality of scintillation pixels including a first and second scintillation pixel, wherein each of the first and second scintillation pixels has:
- a proximal end,
- a distal end opposite the proximal end;
- and
- a first mask disposed around a periphery of the distal end of the first scintillation pixel, wherein the first mask includes a photon absorbing material;
- an optical interface coupled to the distal ends of the first and second scintillation pixels;
- a first photon sensor optically coupled to the distal end of the first scintillation pixel via the optical interface;
- and
- a second photon sensor optically coupled to the distal end of the second scintillation pixel via the optical interface.
