摘要： A method of manufacturing a radiation-detecting device including spaced first columnar scintillators, second columnar scintillators which are located between the neighboring first columnar scintillators and which are spaced from the first columnar scintillators, and photodetecting elements overlapping with the first columnar scintillators includes a step of preparing the substrate such that the substrate has a surface having an uneven section having protruding portions and a plurality of spaced flat sections surrounded by the uneven section and also includes a step of forming the first columnar scintillators and the second columnar scintillators on the flat sections and the protruding portions, respectively, by depositing a scintillator material on the substrate having the uneven section and the flat sections. The uneven section has recessed portions and satisfies the following inequality: h/d≧1 where h is the depth of each recessed portion and d is the distance between the protruding portions.

摘要： A position detector includes a photodetector having photodetecting elements; and a scintillator crystal having uniaxial optical anisotropy. The scintillator crystal is continuous in a uniaxial direction, is disposed on the photodetector such that the uniaxial direction is not perpendicular to the normal to a photodetecting surface, and has a length at least three times the pitch of the photodetecting elements. The uniaxial anisotropy allows at least 4% of scintillation light emitted from a region farthest above the photodetecting surface to reach the photodetecting elements, and allows from 4% to 35% of scintillation light emitted from a region closest to the photodetecting surface to reach the photodetecting elements.

摘要： A radiation detector including a scintillator structure comprising a first plane and a second plane which are not positioned on the same plane, the scintillator structure having an optical waveguiding property in a direction between the first plane and the second plane; and a two-dimensional light receiving element formed of multiple pixels which are disposed parallel to either one of the first plane and the second plane. The radiation detector includes at least one smoothness-deteriorate region which is positioned in one of the first plane and the second plane of the scintillator structure and has an area of 1/6 or more of a light receiving area of each of the multiple pixels. The region is repaired by an optically transparent material so as to be smoothed.
