RADIATION DETECTOR

摘要

A radiation detector (1) includes a three-dimensional stacked scintillator (12) that includes a plurality of scintillator blocks (13) arranged in a matrix in a three-dimensional manner so as to form a prism, in which interposed layers (15) which have a refractive index different from a refractive index of the scintillator blocks (13) and/or have a characteristic of absorbing or scattering some of light emitted by the scintillator blocks are disposed, out of boundary surfaces between the plurality of scintillator blocks (13), on the boundary surfaces extending in a direction perpendicular to a height direction H of the prism, and light blocking layers (14) which block transmission of light emitted by the scintillator are disposed on at least some of the boundary surfaces extending in a direction parallel to the height direction of the prism.

1. A radiation detector comprising:
a three-dimensional stacked scintillator that includes a plurality of scintillator blocks arranged in a matrix in a three-dimensional manner so as to form a prism, in which interposed layers which have a refractive index different from a refractive index of the scintillator blocks and/or have a characteristic of absorbing or scattering some of light emitted by the scintillator blocks are disposed on, out of boundary surfaces between the plurality of scintillator blocks, the boundary surfaces extending in a direction perpendicular to a height direction of the prism, and light blocking layers which block transmission of light emitted by the scintillator blocks are disposed on at least some of the boundary surfaces extending in a direction parallel to the height direction of the prism; and light receiving elements that are provided so as to form a pair on both end surfaces of the prism of the three-dimensional stacked scintillator in the height direction, and receive light emitted by the scintillator blocks so as to convert the light into electrical signals.
