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: An operation device comprises a detector configured to detect an operation on a virtual switch by an operator to operate an X-ray irradiation in an X-ray diagnosis apparatus, wherein the virtual switch is virtually set at a position settled relatively with respect to the operator and output circuitry configured to output a detection result of the operation detected by the detector to the X-ray diagnosis apparatus to be operated. This device eliminates the need for looking away from a display monitor every time the operator operates the X-ray diagnosis apparatus.

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: According to one embodiment, an X-ray diagnostic apparatus comprising: an arm, a pair of grooved portions, a plurality of rollers, and a plurality of belts. The arm is configured to support an X-ray tube at one end and an X-ray detector at another end and has a shape of an arc. The grooved portions are formed on side surfaces of the arm. The plurality of rollers are configured to run in the grooved portions and slidably support the arm along the arc. Each of the belts passes over at least two of the rollers and at least partially abuts on inner walls of the grooved portions.
