Abstract
A scintillator array includes: a structure having scintillator segments and a first reflective layer, the first reflective layer being provided between the scintillator segments and being configured to reflect light, and the scintillator segments having a sintered compact containing a rare earth oxysulfide phosphor; and a layer having a second reflective layer provided above the structure, the second reflective layer being configured to reflect light. The first reflective layer has a portion extending into the layer.
Claims16
A scintillator array comprising:
- a structure comprising scintillator segments and a first reflective layer, wherein the scintillator segments have a sintered compact and the first reflective layer has a resin, wherein the scintillator segments comprise first scintillator segments and second scintillator segments, wherein the first scintillator segments are arranged in a vertical direction and the second scintillator segments are arranged in a horizontal direction, and wherein the first reflective layer is provided between the first scintillator segments and between the second scintillator segments and is configured to reflect light;
- and
- a layer comprising a second reflective layer provided on the structure, the second reflective layer being configured to reflect light,
- wherein the first reflective layer has a protruding portion protruding from a surface of the scintillator segments and extending into the layer both between the first scintillator segments and between the second scintillator segments.
A method for manufacturing a scintillator array, comprising:
- bonding a sheet for scintillator segments and a layer comprising a second reflective layer, the second reflective layer being configured to reflect light;
- partially removing the sheet to form the scintillator segments and a groove, wherein the scintillator segments have a sintered compact, wherein the scintillator segments comprise first scintillator segments and second scintillator segments, wherein the first scintillator segments are arranged in a vertical direction and the second scintillator segments are arranged in a horizontal direction, and wherein the groove is provided between the first scintillator segments and between the second scintillator segments and extends into the layer both between the first scintillator segments and the second scintillator segments through the sheet;
- and
- filling a resin and reflective particles into the groove to form a first reflective layer.
