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.

Claims (13)

1. A laminated scintillator panel comprising:

a scintillator layer converting X-ray radiation into visible light, the scintillator layer comprising scintillator particles bound within an adhesive resin; and

a non-scintillator layer;

wherein the scintillator layer and the 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 and has a transmittance in a lamination direction of at least 80%,

wherein the ratio of scintillator layer thickness to non-scintillator layer thickness is between 30/70 and 70/30.

2. The laminated scintillator panel according to claim 1 , wherein a lamination pitch of the scintillator layer and the non-scintillator layer is from 0.5 to 200 μm.

3. The laminated scintillator panel according to claim 1 , wherein the scintillator particles contain at least either CsI or Gd 2 O 2 S as a main component.

4. The laminated scintillator panel according to claim 1 , wherein the non-scintillator layer comprises a polymer film as a main component.

5. The laminated scintillator panel according to claim 1 , wherein

when i) the radiation incident side is defined to be a first surface, and ii) a side facing the first surface is defined to be a second surface,

a lamination pitch of the scintillator layer and the non-scintillator layer on the second surface is larger than a lamination pitch of the scintillator layer and the non-scintillator layer on the first surface.

6. The laminated scintillator panel according to claim 5 , wherein both the first surface and the second surface are planar.
