摘要： An X-ray imaging system that allows X-ray images to be acquired from a desired direction by considering the tilt of a tabletop. The X-ray imaging system includes a support unit that holds an X-ray imaging unit that performs X-ray imaging of a subject. The subject is placed on the tabletop. A memory stores in advance imaging angle information from previous imaging. A tilt detector detects the tilt angle of the tabletop. A calculator calculates a correction angle for correcting the imaging angle information based on the imaging angle information and on the tilt angle. A drive unit moves the support unit to a position based on the imaging angle information and the correction angle.

摘要： A protection cover includes a pressure responsive means mounted within the cover along its inner wall surface and which operates responsive to external forces to be exerted upon contact with a neighboring object. The protection cover is provided at a portion where physical contact may occur between any of movable or rotating component devices of an X-ray diagnostic apparatus, such as, an X-ray exposure unit or an image intensifier, and a neighboring object which is in the path of the component devices, such as, a subject or a catheter table. The protection cover may, for example, be provided at a moving end of a component X-ray diagnostic apparatus, such as, the forward end of the image intensifier, or may be mounted, instead of being mounted on a movable component device, on a neighboring object at its side facing to the movable part of the component devices, such as, a stand section of the catheter table, which lies in the path of a moving part of the X-ray radiographing component devices.

摘要： An X-ray beam limiting apparatus, is used for a stereoscopic X-ray tube with two focal points separated from each other by a distance of approximately 35 mm. The X-ray beam limiting apparatus includes pivotable blade means for beam-limiting inner edges of pyramid-shaped X-ray beams emitted from the first and second X-ray focal points, while pivoting around center lines of first and second pivotable shafts positionally shifted with each other; and, first slidable blade means for beam-limiting outer edges of the pyramid-shaped X-ray beams emitted from the first and second X-ray focal points, while sliding on a plane substantially perpendicular to travelling paths of the pyramid-shaped X-ray beams.

摘要： In order to perform stereoradiography, an X-ray apparatus utilizes an X-ray tube having a pair of X-ray focal points. The X-ray beams are alternately irradiated from the focal points toward an image intensifier through a patient and are limited by an X-ray beam limiting device. The device shapes the irradiated X-ray beams onto a circular detection surface of the image intensifier into a polygon such as octagon. The X-ray irradiation field on the detection surface can be circumscribed to a circular input window (i.e. effective input area), preventing the field from going beyond the detection surface. Thus, direct X-ray leaking over the image intensifier is avoidable.
