  • Patent number: 11123037
    Abstract: An X-ray imaging apparatus includes an X-ray source, a detector for detecting X-rays, an imaging unit, an operation unit, a notification unit, and a control unit. The control unit generates an image of an inside of an examination room. Further, when detecting that a person other than a subject is present in the examination room based on the image of the inside of the examination room, the control unit performs control to issue caution information indicating that a person other than a subject is present in the examination room.
