Abstract: According to one embodiment, an X-ray diagnostic apparatus includes an X-ray tube, an X-ray variable diaphragm, an X-ray detector, and processing circuitry. The X-ray tube irradiates X-rays. The X-ray variable diaphragm limits an irradiation region of the X-rays. The X-ray detector detects the X-rays that have passed through an object. The processing circuitry controls a movement of the X-ray tube, the X-ray detector, and an aperture of the X-ray variable diaphragm such that, when the irradiation region on the X-ray detector moves within an imaging range, a movement velocity of the irradiation region relative to the imaging range is maintained constant.

Abstract: A console device according to an embodiment includes an operation assembly, a display section, and processing circuitry. The operation assembly includes a plurality of operation sections configured to designate a position of each of four X-ray aperture blades included in an X-ray aperture that limits an irradiation range of an X-ray with which a subject is irradiated from an X-ray tube. The display section is configured to indicate a first irradiation range formed by the X-ray aperture. The processing circuitry is configured to control, according to an operation on the operation assembly, a position of a corresponding X-ray aperture blade and cause the X-ray aperture to form a second irradiation range.

Abstract: An X-ray diagnosis apparatus according to one embodiment includes an imaging system, a display, processing circuitry and system control circuitry. The imaging system includes an X-ray tube that generates an X-ray, an X-ray diaphragm that restricts an irradiation range of the X-ray, an X-ray detector that detects the X-ray, and a couch on which a subject is to be laid for irradiation with the X-ray. The display displays an X-ray image with numerical values indicating positions on the X-ray image generated by X-ray imaging of the subject by the imaging system. The processing circuitry recognizes a numerical value based on a collected user's utterance with respect to the numerical values. The system control circuitry performs control of the imaging system in accordance with a position indicated by the recognized numerical value among the numerical values.

Abstract: An x-ray diagnosis apparatus according to an embodiment includes an x-ray tube holder, a supporter, an ultraviolet ray, a contact portion detector, and an irradiation controller. The x-ray tube holder holds an x-ray tube. The supporter movably supports the x-ray tube holder. The ultraviolet ray emitter is disposed to the x-ray tube holder and emits ultraviolet rays. The contact portion detector detects a contact portion touched by a subject of detection, which is at least one of a subject of examination and an examination technician. The irradiation controller controls the support to move the x-ray tube holder to a position corresponding to the contact portion, and controls the ultraviolet ray emitter to emit the ultraviolet rays toward the contact portion.

Abstract: An X-ray image processing apparatus of an embodiment includes processing circuitry. The processing circuitry acquires fluoroscopy-related information indicating at least one of a fluoroscopic image and a condition for collecting the fluoroscopic image. The processing circuitry evaluates the image quality of the fluoroscopic image based on the fluoroscopy-related information. The processing circuitry outputs identification information identifying whether to save the fluoroscopic image based on the evaluation result.

Abstract: An X-ray diagnostic apparatus according to an embodiment includes a couchtop, an irradiation unit, a support member, a first opening, and an X-ray detector. The couchtop is a component on which a subject is placed. The irradiation unit outputs X-rays from above the subject. The support member supports both ends of the couchtop in the lateral direction from below and forms a gap between the support member and the couchtop in a center part corresponding to an area excluding both ends. The first opening is formed at either one or both of the ends of the couchtop in the longitudinal direction and is accessible to the gap. The X-ray detector is provided in the gap through the first opening and detects the X-rays.
