RADIATION IMAGING APPARATUS AND RADIATION IMAGING SYSTEM

摘要

A radiation imaging apparatus comprising: a detection apparatus having detection regions; at least one plate having transmitting regions arranged in an array for adjusting the amount of radiation incident on the detection regions by blocking radiation incident on a region other than the transmitting regions; a holding unit that holds the plate in such a manner that the plate can move along the detection surface while being kept in a position over the detection surface of the detection apparatus; and a drive unit that moves the plate, is provided. The drive unit can fix the plate in various positions relative to the detection surface, and the area of a part of the detection region on which radiation transmitted through the plate is incident varies depending on the position of the plate.
