  • Patent number: 10499868
    Abstract: According to one embodiment, an X-ray diagnostic apparatus includes an imaging apparatus, processing circuitry and permission input circuitry. The imaging apparatus includes an imaging system performing X-ray imaging of an object, and a bed on which the object is placed. The processing circuitry accepts an instruction to cause the imaging apparatus to perform a operation, and notifies a content of the operation relating to the accepted instruction to a first user. The permission input circuitry accepts information indicating permission of the operation from the first user who has confirmed the content of the operation. The processing circuitry causes the imaging apparatus to perform the operation to more severely restrict the operation compared with after acceptance of information indicating permission of the operation by the permission input circuitry, until the acceptance of information indicating permission of the operation by the permission input circuitry.
