Abstract
Artifacts in a tomographic image of a subject including a cyclically moving object to be treated are reduced. A radiographic imaging device includes: a gantry that is equipped with two sets of radiation sources and detectors which are used in pairs, the gantry rotating the radiation sources and the detectors around a subject; and a reconstruction section that reconstructs a tomographic image of the subject based on multiple projection images generated from output of the detectors. The radiographic imaging device further includes: a phase calculation section; a divide section that divides, on a phase-by-phase basis, first projection image groups of multiple projection images acquired by the first set, and similarly second projection image groups acquired by the second set; and a condition setting section. The reconstruction section reconstructs a tomographic image by use of the first and second projection image groups that are placed in the same phase.
