Abstract
A structured scintillator and a detection system employing structured scintillators. More specifically, a structured scintillator comprising a scintillator material having a plurality of isolated structures is disclosed. The structures may be conical in shape. The structures may be formed on a substantially transparent material layer which has been patterned to form a plurality of isolated regions. The structures may be formed on top of the isolated regions to provide isolated scintillator structures having space therebetween. The isolated regions and scintillator structures may be aligned with underlying detection devices.
Claims33
A structured scintillator comprising:
- a flexible substrate;
- a substantially transparent material layer disposed on the flexible substrate and patterned to provide a plurality of isolated regions;
- and
- a scintillator material disposed on the substantially transparent material layer and comprising a plurality of isolated structures.
A structured scintillator comprising:
- a substrate;
- a substantially transparent material layer disposed on the substrate and patterned to provide a plurality of isolated regions;
- and
- a scintillator material disposed on the substantially transparent material layer and comprising a plurality of conical structures.
A scintillator comprising a material structured to form a plurality of conical structures configured to guide photons, wherein each of the plurality of conical structures comprises a top portion configured to receive incident radiation and a bottom portion configured to emit photons, wherein the bottom portion is narrower than the top portion.
A detection system comprising:
- a photo detection array comprising a plurality of detectors configured to detect light emissions;
- and
- a scintillator configured to receive incident radiation and emit photons toward the photo detection array, wherein the scintillator comprises a plurality of isolated structures.
A method of fabricating a scintillator comprising:
- patterning a substantially transparent material onto a substrate to provide a plurality of isolated regions of the material on the substrate;
- and
- forming a conical scintillator structure on each of the plurality of isolated regions.
