According to one embodiment, an X-ray detection unit for a wheelchair includes a container and an attachment portion coupled with the container. The container is configured to contain a flat X-ray detector. The attachment portion is configured to be detachably mounted to a part of the wheelchair in which a subject is seated, so that a detection plane of the X-ray detector in the container faces the subject.

X-ray detection unit for wheelchair, and X-ray diagnostic apparatus

According to one embodiment, an X-ray diagnostic apparatus includes an X-ray tube, a driver, a supporter, and processing circuitry. The X-ray tube including a rotating anode. The driver rotates the rotating anode. The supporter supports the X-ray tube in an inclinable manner. The processing circuitry acquires information indicating an attitude of the supporter and controls the driver based on information indicating the acquired attitude.

X-ray diagnostic apparatus and X-ray high-voltage generator

An X-ray diagnostic apparatus comprises an X-ray tube and processing circuitry. The X-ray tube includes a rotary anode. The processing circuitry is configured to derive an acquiring condition from a fluoroscopic image, and start to increase, in accordance with the acquiring condition derived, a rotating speed of the anode from a low rotating speed to a high rotating speed before the X-ray tube finishes emitting an X-ray to acquire the fluoroscopic image.

X-ray diagnostic apparatus and medical-information processing apparatus configured to control a rotating speed of a rotary anode of an X-ray tube by deriving an acquiring condition from a fluoroscopic image

An X-ray diagnostic apparatus according to embodiments includes an X-ray tube assembly and a grid potential control circuitry. The X-ray tube assembly includes a filament that emits electrons, a target that generates X-rays by receiving the electrons, and a grid having a potential for adjusting a potential gradient around the filament. The grid potential control circuitry switches the potential of the grid to a potential where the potential gradient around the filament becomes greater than a potential gradient generated by a potential of the filament and a potential of the target.

X-ray diagnostic apparatus

According to one embodiment, An X-ray diagnostic apparatus includes an X-ray generator that generates X rays, an X-ray detector that detects the X rays generated by the X-ray generator and having passed through a subject, an X-ray restrictor that restricts an irradiation range on a detection surface of the X-ray detector of the X rays generated by the X-ray generator, a signal input unit that inputs a biomedical signal related to the subject, a signal detector that detects a biomedical change from the biomedical signal and also outputs an extension switching signal, and an X-ray restrictor controller that controls the X-ray restrictor such that the irradiation range of the X rays is extended in response to output of the extension switching signal.
