Abstract: A radiography apparatus includes an upright imaging stand that is used for radiography on a subject, a camera as a detection sensor that immediately detects a state of the subject with respect to the upright imaging stand, a tablet terminal, and a reflective member. The tablet terminal displays a notification screen including an image output from the camera. The reflective member reflects the notification screen such that the subject facing the upright imaging stand visually recognizes the image.

Abstract: A CPU of a console comprises a color image acquisition unit, a distance image acquisition unit, a specification unit, and an estimation unit. The color image acquisition unit acquires a color image, in which a patient and a periphery of the patient are captured, from a visible light camera. The distance image acquisition unit acquires a distance image indicating a distance between a radiation tube and an object, from a TOF camera. The specification unit specifies a kind of the object in the color image. The estimation unit estimates intensity of radiation in an environment captured in the color image based on reference information including the distance image and a specification image as a specification result of the kind of the object.

Abstract: A medical imaging device that includes: a press plate that presses a breast; an emitter that radiates radiation onto the breast; an acquisition section that acquires various information indicating a type of an acoustic matching member inserted between the press plate and the breast in cases in which ultrasound imaging of the breast is performed; and a setting section that sets a tube voltage of the emitter to a first tube voltage, in cases in which radiographic imaging of the breast is performed alone, and that sets the tube voltage of the emitter to a second tube voltage that is different from the first tube voltage, by employing the various information acquired by the acquisition section, in cases in which radiographic imaging and ultrasound imaging of the breast are performed consecutively with the acoustic matching member still inserted.
