Abstract: An X-ray diagnostic apparatus of an embodiment includes processing circuitry. The processing circuitry acquires an image of a movable range of a movable unit that can move freely in an examination room where X-ray imaging of a subject is performed, from a camera provided in the examination room, determines the classification of an object present in the movable range on the basis of the image, and controls the operation of X-ray imaging on the basis of the determination results.

Abstract: In one embodiment, an X-ray diagnostic apparatus includes a memory and processing circuitry. The processing circuitry causes the memory to store a movement path that is defined by a combination of movements of a plurality of movable shafts of an imaging apparatus and is generated based on movements of the imaging apparatus in response to a user's operation. The processing circuitry moves the imaging apparatus in a reverse order of the movement path stored in the memory.

Abstract: An X-ray diagnostic device according to embodiments includes an X-ray tube, an X-ray detector, a couchtop, a drive mechanism, an input interface, and processing circuitry. The X-ray tube emits X-rays to a subject. The X-ray detector detects X-rays transmitted through the subject. The couchtop has the subject placed thereon. The drive mechanism generates the driving force for moving the couchtop. The input interface accepts instruction operations from an operator regarding the movement of the couchtop. The processing circuitry acquires one of a weight applied to the couchtop and a deflection amount of the couchtop, and determines the driving force to be generated by the drive mechanism based on one of the weight and the deflection amount and on the instruction operation.

Abstract: The X-ray imaging apparatus according to the embodiment includes an X-ray irradiator and processing circuitry. The X-ray irradiator is placed in a surgery room. The processing circuitry is configured to sequentially acquire a position of each staff member presenting in the surgery room during a procedure using the X-ray irradiator. The processing circuitry is configured to sequentially acquire an exposure dose of each staff member from a dosimeter. The processing circuitry is configured to associate the position of each staff member and the exposure dose of each staff member with a time, and sequentially record association data in a memory circuit. The processing circuitry is configured to display association data indicating a relation between the position of each staff member and the exposure dose of each staff member in an identifiable manner on a display.
