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： Provided is a radiation detecting element, including: needle crystal scintillators and a protruding pattern in which: one end of the needle crystal scintillators is in contact with of upper surfaces of the multiple protrusions; a gap corresponding to a gap between the multiple protrusions is provided between portions of the needle crystal scintillators in contact with the upper surfaces of the multiple protrusions; and a number of the needle crystal scintillators in contact with one of the upper surfaces is 5 or less. Conventionally, since the needle crystals exhibit a state of a polycrystalline film in an early stage of vapor deposition, and light also spreads in a horizontal direction, the light received by a photodetector portion and the spatial resolution was lower than ideal values. The present invention enables the deviating region to be the ideal state in an early stage of growth.
