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.

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： An X-ray imaging apparatus includes a phase grating, an absorption grating, a detector, and an arithmetic unit. The arithmetic unit executes a Fourier transform step of performing Fourier transform for an intensity distribution of a Moiré acquired by the detector, and acquiring a spatial frequency spectrum. Also, the arithmetic unit executes a phase retrieval step of separating a spectrum corresponding to a carrier frequency from a spatial frequency spectrum acquired in the Fourier transform step, performing inverse Fourier transform for the separated spectrum, and acquiring a differential phase image.
