  • Patent number: 10775518
    Abstract: Provided is a method of manufacturing a lattice-shaped laminated scintillator panel capable of enlarging the area and increasing the thickness with a means completely different from a conventional technique using a silicon wafer. A method of manufacturing a laminated scintillator panel having a structure in which a scintillator layer and a non-scintillator layer are repeatedly laminated in a direction substantially parallel to the direction of radiation incidence, the method including: a step of forming a laminate by repeatedly laminating the scintillator layer and the non-scintillator layer; and a joining step of pressurizing the laminate to join the scintillator layer and the non-scintillator layer integrally.

  • Patent number: 10761220
    Abstract: A laminated scintillator panel having a structure in which a scintillator layer for converting radiation into visible light and a non-scintillator layer are repeatedly laminated in a direction parallel to an incident direction of radiation, wherein the non-scintillator layer transmits the visible light. Provided is a lattice-shaped laminated scintillator panel with high luminance, a large area, and a thick layer by means completely different from a conventional technique using a silicon wafer.
