Provided is a radiographic apparatus with safety and time-saved imaging upon inclination of a subject without pulling an external instrument by the subject. In the radiographic apparatus, a top board supporting the subject placed thereon is rotatable and liftable. The characteristic feature of the embodiment is to control a level of an intersection of the top board and a line connecting an X-ray tube to an FPD to be constant in association with operation of a top-board rotation controller. This achieves a constant level of a region of interest (a site to be imaged) of the subject regardless of rotation of the top board. Consequently, an invariable distance is obtainable between the subject and the external instrument on the floor, allowing suppression in pulling of the external instrument due to a vertical movement of the subject. As a result, provision of a radiographic apparatus with safety and time-saved imaging is obtainable. |
