    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.

    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.
