PROBLEM TO BE SOLVED: To provide a radiation imaging system capable of generating an image of a DSA (Digital Subtraction Angiography) system with simple sequence control.SOLUTION: A radiation imaging system which performs difference processing by using a mask image retained on the basis of a radiation image acquired before injection of a contrast medium and a radiation image acquired after injection of the contrast medium, displays a first diagram 605 indicating first timing at which exposure of radiation is started, a second diagram 603 indicating second timing for retaining the mask image, and a third diagram 604 indicating third timing for starting injection of the contrast medium along a temporal axis 602 in this order. On the basis of the second diagram 603 and the third diagram 604, when one of the second diagram 603 and the third diagram 604 moves along the temporal axis 602, a control part controlling the second timing and the third timing moves the other of the second diagram 603 and the third diagram 604 so that the interval between the first diagram 605 and the third diagram 604 becomes larger than the interval between the first diagram 605 and the second diagram 603. |
