Title:
GRID AND X-RAY DETECTOR HAVING GRID
Document Type and Number:
WIPO Patent Application WO/2020/059544
Kind Code:
A1
Abstract:
This grid according to the present invention is used together with an X-ray detector for capturing an X-ray image of a subject. The X-ray detector is configured by two-dimensionally arranging a plurality of pixels each including an imaging unit and a non-imaging unit provided adjacent to the imaging unit, and the grid is configured by alternately arranging a plurality of X-ray absorbing units and a plurality of X-ray transmitting units, and is externally installed adjacent to the surface of the X-ray detector. In such a grid, when the grid is viewed in plan view in a state of being adjacent to the surface of the X-ray detector, at least some of the X-ray absorbing units overlap the imaging unit of the X-ray detector, and the state of overlap between the X-ray absorbing units and the imaging unit changes. Further, the grid comprises the plurality of X-ray absorbing units having the same state of overlap with the imaging unit at a predetermined cycle.
