Claim One:
1. A radiation image capturing device comprising: a detector panel including a collimator that aligns an incident direction of a radioactive ray and a detector that detects the radioactive ray, the incident direction of which is aligned by the collimator; a gantry mounted with one or a plurality of the detector panels, the gantry performing a rotational movement of the mounted detector panel around a circumference, an object being substantially a center of the circumference; and a tangential direction moving mechanism that moves, in a tangential direction of the rotational movement, the one detector panel or the plurality of the detector panels mounted on the gantry, wherein when the gantry performs the rotational movement of the one detector panel or the plurality of the detector panels around the entire circumference of the object and a projection image of the region of interest at each rotational position is captured by the one detector panel or the plurality of the detector panels, the one detector panel or each of the plurality of the detector panels is moved in the tangential direction so that a size of a union of a capturing range of the projection image captured by the one detector panel or each of the plurality of the detector panels corresponds to a size of the region of interest, and the projection image captured by the one detector panel or each of the plurality of the detector panels that have performed the rotational movement and the tangential direction movement is used to reconstruct a transaxial image of the region of interest.
