Provided is a radiation imaging device that corrects position shift between a collimator and a detector and by which an image without artifacts can be obtained. The device is configured to be provided with a detector (21) for measuring radiation, a collimator (26) that has a through-hole (27) in which one or a plurality of detectors (21) are disposed and that restricts the direction of incidence of the radiation, and a position shift measuring means that measures the position shift between the detector (21) and the collimator (26) by way of a profile of a radiation source measured by the detector (21) on the basis of the radiation source disposed to correspond to a prescribed detector (21). |
