Abstract:
1. A radiation imaging apparatus, comprising: a radiation source; a reflective structure in which a radiation detector; and an image construction unit arranged to construct an image of an object based on an intensity of the radiation which is emitted from each of the passages, transmitted through the object, and is detected by the radiation detector, wherein when one edge of the reflective structure is an inlet of the radiation and the other edge is an outlet of the radiation, a pitch of the reflective substrates at the outlet is larger than a pitch of the reflective substrates at the inlet, wherein when a virtual plane is set in a position which is separated from the reflective substrates at both sides of the passage with the same distance, the radiation source is disposed on tangential planes of a plurality of virtual planes at the inlet and the tangential planes of the plurality of virtual planes at the outlet are approximately parallel to each other, and wherein if the interval between adjacent reflective substrates is constant and a thickness of the reflective substrate at an outlet side is larger than a thickness of the reflective substrate at an inlet side, a penumbra amount Δ  where L
