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.

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: An exposure management system according to an embodiment includes a processing circuitry. The processing circuitry is configured to calculate a deviation index related to a difference between a target exposure index indicating an index of an exposure value that is set as a target of an X-ray image taking process and an image-taking-period exposure index indicating an index of an exposure value observed during the X-ray image taking process. The processing circuitry is configured to control so as to cause a display device to display history information from a predetermined time period indicating at least one selected from between image-taking-period exposure indices and deviation indices.
