PROBLEM TO BE SOLVED: To effectively provide accurate radiation images when acquiring the radiation images in a plurality of photographing positions like a phase- contrast photographing method. SOLUTION: In this method, a detection panel 31 is irradiated with X-rays 12 transmitted through a subject 21 with moving the detection panel 31, and image data Sn showing the X-ray images of the subject 21 are obtained in the plurality of photographing positions. A position sensor 51 detects that the detection panel 31 reaches a predetermined photographing position and outputs a detection signal D. When the detection signal D is inputted to a controller 53, a shutter 52 is driven such that the detection panel 31 is irradiated with the X-rays 12 transmitted through the subject 21. Based on the image data Sn obtained in the plurality of photographing positions, a calculation part 40 obtains the image data S1 showing a phase-contrast image.
