Abstract: According to one embodiment, an X-ray diagnostic apparatus includes an X-ray irradiator, a scatterer, a grid, and a detector. The X-ray irradiator irradiates X-rays. The scatterer is provided between the X-ray irradiator and an object, that scatters the irradiated X-rays. The grid is provided between the scatterer and the object, that transmits the scattered X-rays within a predetermined angular range. The detector detects X-rays transmitted through the object together with an incident angle of the X-rays.

Abstract: A wrap replacing apparatus according to the embodiments includes: an insertion port into which a medical device wrapped in a first bag is inserted; a peeler configured to peel off the first bag from the medical device inserted into the insertion port; a wrapper configured to wrap in a second bag the medical device from which the first bag is peeled off; and a take-out port from which the medical device wrapped in the second bag is taken out.

Abstract: An X-ray diagnosis apparatus includes a holding device, a drive unit, a route specify unit, an operation direction detector, and a drive controller. The holding device holds an X-ray tube and is configured to be movable. The drive unit is capable of moving the holding device. The route specify unit specifies a movement route from a current position of the holding device to a target position. The operation direction detector detects operation direction, which is the direction of moving operation that the holding device has received. The drive controller controls the drive unit to stop a driving force when the operation direction differs from the direction of the movement route.

Abstract: According to one embodiment of an X-ray imaging system, a column, including a first sub column, a second sub column, a third sub column, a first connector, and a second connector, supports an X-ray tube. The first connector connects the second sub column to the first sub column and includes a first rotation axis parallel to a short axis of a tabletop. The second connector connects the third sub column to the second sub column and includes a second rotation axis perpendicular to the first rotation axis and a central axis of the second sub column. The third sub column supports the X-ray tube.

Abstract: In a system for exposing X-ray film to X-rays, to adequate density, X-rays emitted from a X-ray tube and passing through an object are incident on a X-ray film through a X-ray pickup device. A X-ray pickup device having a plurality of pickup fields comprises an intensifying screen for converting X-rays into light rays. In each of the pickup fields, a bundle of optical fibers are extended and end faces of the fibers are so arranged as to occupy each of the pickup field with segment pickup field of the optical fibers. The optical fiber bundles are optically coupled to photodetectors, respectively so that light rays are converted into electrical signals.
