PROBLEM TO BE SOLVED: To prevent interference of an imaging system and a holder part with a subject, and to securely set an appropriate interference area permitting efficient radiography. SOLUTION: In the radiography with the holder part 81 of a holder device 8 having an X-ray generating part 2 and an X-ray detection part 3 (the imaging system) being moved or rotated in the periphery of the subject 150, a weight detection part 15 detects weight information of the subject 150 mounted on a top plate 91 of a bed part 9, and an interference area setting part 122 sets the interference area of an appropriate size in the periphery of the subject 150 based on the weight information and the positional information of the top plate 91. Next, the imaging system is moved or rotated together with the holder part 81 at prescribed speed under the observation of radiographic data, and the imaging system is moved/rotated to an appropriate position for the radiography at reduced speed of movement/rotation if a part of the imaging system or holder part 81 reaches the interference area.
