PROBLEM TO BE SOLVED: To improve a resolution at the time of acquiring radiation dynamic images. SOLUTION: The electrocardiogram of an object 3 is detected and five time phases from the 1st time phase to the 5th time phase are allocated to a pulsation cycle (1 second). First irradiation with an X-ray L is performed in the 1st time phase of the 1st beat and a radiation image is acquired. Successively, the irradiation with the X-ray L is performed in the 2nd time phase of the 2nd beat, the 3rd time phase of the 3rd beat, the 4th time phase of the 4th beat and the 5th time phase of the 5th beat, and image signals are respectively outputted. Five radiation images acquired in such a manner are combined at the interval of 0.2 second and the radiation dynamic image is generated. By displaying the radiation dynamic image, the pseudo moving image of one pulsation is displayed. Also, since each irradiation with the X-ray L is at the interval of 1.2 second, the image signals from the 1st time phase to the 5th time phase are acquired by the high resolution.
