PROBLEM TO BE SOLVED: To provide a radiographic apparatus capable of accurately overlapping a blood vessel image with a live image even if a top board moves during moving image shooting.SOLUTION: A radiographic apparatus includes a stereoscopic image editing section 13 which moves a blood vessel image of a subject on data in accordance with the movement amount of a top board 2 output from a potentiometer 25. However, if trying to grasp the movement of the top board 2 only based on the potentiometer 25, a deviation occurs at the time of overlapping of a moving image and the blood vessel image. In this invention, the movement of the top board 2 is actually measured by imaging a phantom in plural times while changing the position of the top board 2. By considering the actually-measured data, the moving image and the projection image can be overlapped with each other without a deviation even if there are an error in the potentiometer 25 and a deviation in the movement direction of the top board 2.
