PROBLEM TO BE SOLVED: To obtain a radiographic image which is suitable to three-dimensional analysis of the moving state of a joint, etc., while suppressing an exposure on a subject and a cost in a radiographing apparatus. SOLUTION: An operating part 8 inputs a plurality of movement phases Arj to be concerned in the reciprocative movement of the subject 1. A radiographing means performs radiographing at each point of time when the movement phase Ag of the subject 1 which is detected by a movement phase detector 7 coincides with each movement phase Arj to be concerned, concerning a plurality of respectively different directions through the use of a pair of X-ray tubes 2 and an X-ray detector 3 such as a flat panel detector.
