<P>PROBLEM TO BE SOLVED: To provide a scattered ray absorption grid in which radiation is emitted from two irradiation directions where an intermediate direction intersects the direction perpendicular to a grid surface, which avoids the reduction of transmissivity and enlargement to equalize the transmissivity in both directions while removing scattered ray including a parallax direction component. <P>SOLUTION: Shield members 51, which are plate-like members, are arranged spaced apart in a projection direction in which the intermediate direction D3 is projected on the grid surface. In addition, the members are arranged so that the ratio of the radiation passing through the space among the radiation emitted from one irradiation direction D1 and the ratio of the radiation passing through the space among the radiation emitted from the other irradiation direction D2 are equalized. <P>COPYRIGHT: (C)2013,JPO&INPIT |
