20100260315 | SOURCE GRATING FOR TALBOT-LAU-TYPE INTERFEROMETER - A source grating for a Talbot-Lau-type interferometer includes a plurality of channels having incident apertures provided on a side irradiated with X-rays and exit apertures provided on an opposite side of the side irradiated with the X-rays; the exit apertures of the channels have an aperture area smaller than an aperture area of the incident apertures; and the exit apertures of the channels are arranged so that interference fringes of Talbot self-images formed by X-rays exiting from the exit apertures of the adjacent channels are aligned with each other. | 10-14-2010 |
20110026680 | X-RAY GENERATING DEVICE - An X-ray generating device includes an electron-beam generator, a target assembly group, and an electron-beam focusing unit. The electron-beam generator generates electron beams. The target assembly group includes a plurality of target assemblies that are arranged along a straight line in a direction in which X-rays are output; each of the target assemblies includes a target and a supporting member; the target generates X-rays from one of the electron beams generated by the electron-beam generator; and the supporting member supports the target by being disposed adjacent thereto. The electron-beam focusing unit focuses the electron beams onto the targets included in the target assembly group so that X-rays are generated in each of the target assemblies and output along the straight line after passing through the target assemblies. | 02-03-2011 |
20110051889 | X-RAY PHASE GRATING AND METHOD FOR PRODUCING THE SAME - An X-ray phase grating used for X-ray phase-contrast imaging based on Talbot interference includes a first substrate and a second substrate. The first substrate and the second substrate are combined so as to be shifted from each other by one half period. The first substrate has a first pattern in which first faces and second faces making an angle of α (where α≠0 and α≠90° with the first faces are periodically arranged. The second substrate has a second pattern in which third faces corresponding to the first faces and fourth faces corresponding to the second faces and making an angle of α with the third faces are periodically arranged. | 03-03-2011 |

20140270060 | X-RAY TALBOT INTERFEROMETER AND X-RAY TALBOT IMAGING SYSTEM - An X-ray Talbot interferometer includes a source grating configured to spatially split X-rays emitted from an X-ray source, a diffraction grating configured to form an interference pattern with the X-rays from the source grating, and an X-ray detector configured to detect the X-rays from the diffraction grating. The X-ray Talbot interferometer further includes an angle varying unit configured to vary an angle formed by an optical axis, which is the center of a flux of the X-rays from the X-ray source, and the source grating. The angle varying unit varies the angle formed by the optical axis and the source grating from a first angle to a second angle. The X-ray detector detects the X-rays at least when the optical axis and the source grating form the first angle and when the optical axis and the source grating form the second angle. | 09-18-2014 |
20150023465 | SOURCE GRATING, INTERFEROMETER, AND OBJECT INFORMATION ACQUISITION SYSTEM - A source grating includes a first sub-source grating, where first transmitting portions which transmit X-rays, and first shielding portions which shield X-rays, are alternately arranged in a first direction; and a second sub-source grating, where second transmitting portions which transmit X-rays, and second shielding portions which shield X-rays, are alternately arranged in a second direction orthogonal to the first direction. The first sub-source grating is curved so that two positions in the curve align in the first direction. The second sub-source grating is curved so that two positions in the curve align in the second direction. | 01-22-2015 |
20150131783 | RADIATION DETECTION SYSTEM AND RADIATION IMAGING APPARATUS - A radiation detection system comprises at least one detector in which a plurality of detection elements are arranged, wherein each detection element includes a converting portion that converts energy of incident radiations directly into electrical signals and a signal reading portion that reads the electrical signal from the converting portion and outputs the electrical signal, the converting portion including a plurality of protruded portions arranged at intervals, and the plurality of protruded portions are electrically connected to one signal reading portion. | 05-14-2015 |
20150179292 | X-RAY SHIELD GRADING AND METHOD FOR FABRICATING THE SAME - An X-ray shield grating includes a plurality of partial gratings being stacked on each other. In the X-ray shield grating, each of the plurality of partial gratings has a structure in which grating elements, in each of which an X-ray blocking portion and an X-ray transmitting portion are arrayed with a first period, are arrayed with a second period; the first period in each of the plurality of partial gratings is equal to one another; and the second period in each of the plurality of partial gratings is different from one another. | 06-25-2015 |
