Abstract: An X-ray diagnosis apparatus according to the embodiment disclosed herein includes an X-ray tube configured to have a plurality of focal points and configured to emit X-rays from each focal point, a radiation quality filter configured to change radiation quality of the X-rays emitted from each of the focal points, and a mover configured to move the radiation quality filter in a direction along which the focal points are aligned.

Abstract: An X-ray diagnosis apparatus according to the present embodiment comprises: an X-ray irradiator configured to irradiate X-rays; an imager configured to image an identifier that identifies a position of an X-ray detector which detects X-rays; and processing circuitry configured to calculate, based on the identifier shown on an image imaged by the imager, a relative position of the X-ray irradiator regarding the X-ray detector and an irradiation position of the X-ray irradiator where a corresponding relative position meets a predetermined X-ray imaging condition; and output, based on the relative position and the irradiation position, a movement information of the X-ray irradiator.

Abstract: An x-ray diagnostic apparatus according to an embodiment includes a radiographic unit, a movable unit, and processing circuitry. The radiographic unit performs radiography. The movable unit is provided in the radiographic unit and is movable to plural positions. The processing circuitry moves the movable unit to a position where the movable unit and a disinfection apparatus that performs disinfection have a predetermined positional relation to each other.

Abstract: According to one embodiment, an X-ray mammography apparatus includes a breast support, a compression plate, and a compression controller. The breast support where the breast is placed. The compression plate is arranged such that the breast is sandwiched between the breast support and the compression plate. The compression controller is configured to control the breast support to move toward the compression plate so as to compress the breast from below between the breast support and the compression plate.

Abstract: The X-ray imaging system according to the present embodiment includes an X-ray tube, a holding assembly, a flying object, an X-ray detector, and processing circuitry, The X-ray tube is configured to emit X-rays. The holding assembly is configured to hold the X-ray tube. The flying object is equipped with the holding assembly. The X-ray detector is configured to detect the X-rays emitted by the X-ray tube. The processing circuitry is configured to control a flight of the flying object, and to control the flight of the flying object such that the X-ray tube is arranged on a predetermined position with respect to the X-ray detector.

Abstract: According to one embodiment, a compression plate compresses a breast of a subject with the breast between the compression plate and an imaging plane of an imaging table. The compression plate including a compression face and a chest wall face. The compression face is configured to compress the breast to the imaging table. The chest wall face is configured continuously from the compression face to be in contact with a chest wall of the subject during X-ray imaging. The chest wall face includes a second region which is in contact with the chest wall of the subject, and the second region has surface roughness which is greater than that of a first region of the compression face, which is opposed to the imaging table.
