Abstract
It is possible to reduce the weight of an anti-scatter collimator and to improve uniformity of scattered radiation shielding rate. A radiation imaging device has a radiation source, a radiation detector that detects radiation emitted from a focus of the radiation source, and an anti-scatter collimator provided between the radiation source and the radiation detector. The anti-scatter collimator has a septum provided at a predetermined interval along a radiation incident direction on a boundary between pixels of the radiation detector. The upper end of a top septum corresponds with a radiation incident surface.
