20120236988 | X-RAY IMAGING APPARATUS - An X-ray imaging apparatus comprises a grating configured to form an interference pattern by diffracting X-rays from an X-ray source, a amplitude grating configured to partly shield X-rays forming the interference pattern, and an X-ray detector configured to detect an intensity distribution of X-rays from the amplitude grating. The amplitude grating is comprised of a central area and a peripheral area and the peripheral area shows an X-ray transmittance higher than the central area relative to X-rays perpendicularly entering the amplitude grating. | 09-20-2012 |
20130272501 | X-RAY IMAGING APPARATUS - The present invention relates to an X-ray imaging apparatus including an X-ray source, a grating that divides diverging X-rays irradiated from the X-ray source, and a detector that detects X-rays which are divided by the grating and pass through a sample. The grating includes a plurality of transparent objects which pass the diverging X-rays and a plurality of opaque objects that shield the diverging X-rays. A focused position at which a plurality of extended lines intersect each other and the X-ray source are arranged in different position. The extended lines are formed by extending center lines which connect a center of the X-ray source side of each of the plurality of opaque objects facing the X-ray source with a center of the detector side of each of the plurality of opaque objects facing the detector. | 10-17-2013 |
20140037054 | SPECIMEN INFORMATION ACQUISITION SYSTEM - A specimen information acquisition system is provided with a first grating which divides divergent X-rays from an X-ray source to form a plurality of primary X-ray beams, and a second grating which blocks at least a part of each of the primary X-ray beams to form a plurality of secondary X-ray beams. The specimen information acquisition system is further provided with an X-ray detector which detects the secondary X-ray beams and a calculator which calculates information of a specimen arranged between the X-ray source and the X-ray detector. The primary X-ray beams do not overlap each other on each of X-ray transmitting portions of the second grating. The edges of the respective primary X-ray beams enter a plurality of X-ray blocking portions of the second grating. | 02-06-2014 |
20140126690 | X-RAY IMAGING APPARATUS AND X-RAY IMAGING SYSTEM - An X-ray imaging apparatus includes an optical device configured to form a periodic pattern using X-rays radiated from an X-ray source, an alignment mark of the optical device, a first detector, a second detector, and a movement unit configured to change at least either a position of the optical device or an angle of the optical device on the basis of a result of detection performed by the second detector. The first detector detects X-rays that have passed through the optical device and a subject, and the second detector detects X-rays that have passed through the alignment mark. The movement unit includes a movement instruction section that instructs the optical device to move on the basis of the result of the detection performed by the second detector and movement sections that move the optical device on the basis of the instruction issued by the movement instruction section. | 05-08-2014 |
20140270061 | X-RAY TALBOT INTERFEROMETER AND X-RAY IMAGING SYSTEM INCLUDING TALBOT INTERFEROMETER - An X-ray Talbot interferometer includes a first grating configured to diffract X-rays from an X-ray source and form an interference pattern, a second grating configured to block a portion of X-rays that form the interference pattern, and a detector configured to detect X-rays from the second grating. An inspection object is disposed between the X-ray source and the second grating. The second grating includes a first shield grating portion in which a shield portion and a transmissive portion are arranged periodically at a first period and a second shield grating portion. The first period is expressed as ps×n×Ls/(Ls+Lf), where ps denotes a size of pixels that the detector has, n denotes a positive integer, Ls denotes a distance from the X-ray source to the first shield grating portion, and Lf denotes a distance from the first shield grating portion to the detector. | 09-18-2014 |
