RADIOGRAPHIC-IMAGE IMAGING GRID, MANUFACTURING METHOD THEREFOR, AND RADIOGRAPHIC-IMAGE IMAGING SYSTEM

摘要

Provided is a phase-type radiographic-image imaging grid whereby almost no partial loss of X-rays occurs and deterioration over time is minimized. Said phase-type grid (13) is provided with a silicon substrate (41) and a sealing member (43). The following are formed on the surface of said silicon substrate (41): a grid section (42a) that produces a prescribed phase difference between X-rays passing through concave parts (46) and X-rays passing through convex parts (47); and a convex edge section (42b) around the grid section (42a). The sealing member (43) is provided on the surface of the silicon substrate (41) on which the grid section (42a) and edge section (42b) are formed and, at least, abuts against the edge section (42b) and seals the grid section (42a).
