Abstract: An X-ray imaging apparatus implements a fluoroscopy that irradiates a weaker dose of X-rays than a dose on the long-length imaging toward a subject M at each location in the long-length imaging range, while moving an X-ray tube in a body axis direction relative to the subject M prior to the long-length imaging, when the long-length imaging is implemented by moving the X-ray tube 2 in the body axis direction relative to the subject M. The dose D1 at the location having the thick body thickness is less, so that the tube voltage is set up to be high as the tube voltage V1 and vice versa, the dose D2 at the location having the thin body thickness is high, so that the tube voltage is set up to be low as the tube voltage V2.

Abstract: An X-ray imaging apparatus has an X-ray tube that irradiates an X-ray to a subject, an flat panel detector (FPD) that takes an X-ray image on the basis of the X-ray transmitted through the subject, a real-time image synthesis element that synthesizes an image by connecting in turn an image of a plurality of strip-shape X-ray images concurrently taken while letting the X-ray tube and the FPD move relative with respect to the subject, and a real-time image monitor that displays an intermediate image taken by the FPD and is synthesized in turn by the real-time image synthesis element.
