Abstract: An X-ray radioscopic photographing apparatus comprises a top-board support frame for supporting a top board in the body axis direction of an examinee, a stand for supporting the top-board support frame so as to be rotatable about the body axis, a support for holding an X-ray tube unit and an X-ray image intensifier so as to be faced each other, a support member for holding the stand and supporting the support so as to be movable in the body axis direction, and a base portion for supporting the support member tiltably.

Abstract: A digital X-ray photography device, including an X-ray tube unit, a rotation supporting unit for rotating around a subject, an image system unit installed on the rotation supporting unit, for detecting X-rays transmitted through the subject, a first image processing unit, installed on the rotation supporting unit, for constructing a rotational stereoscopic image of the subject based on a signal from the image system unit, an X-ray detector, installed on the rotation supporting unit, for detecting X-rays transmitted through the subject, a second image processing unit, installed on the rotation supporting unit, for constructing a CT image of the subject based on a signal from the X-ray detector, and a unit for controlling pulse-shaped X-rays to be continuously radiated during a forward rotation and a backward rotation of the rotation supporting unit in order to perform a rotational stereoscopic photographing.
