  • Patent number: 10940331
    Abstract: A medical apparatus according to an embodiment includes an acquirer, a corrector, an identifier, and an output controller. The acquirer is configured to acquire a fluoroscopic image of an object from an imager. The corrector is configured to correct an image of one or more predetermined regions used for identifying a target position of the object in the fluoroscopic image based on one or more correction values but does not correct an image of at least a part of a region out of the predetermined region in the fluoroscopic image. The identifier is configured to identify the target position based on an image corrected by the corrector. The output controller is configured to output an irradiation permission signal to a therapeutic device which irradiates the object with a therapeutic beam based on the target position identified by the identifier.

  • Patent number: 10737117
    Abstract: A medical apparatus according to an embodiment includes an acquirer, an identifier, an output controller, a display controller, and an input operation acquirer. The acquirer acquires a fluoroscopic image of a object from an imager which performs imaging by irradiating the object with an electromagnetic wave to generate the fluoroscopic image. The identifier identifies a target position of the object in the fluoroscopic image. The output controller outputs an irradiation permission signal to a therapeutic device which irradiates the object with a therapeutic beam when the target position identified by the identifier is settled within an irradiation permission range. The display controller causes a display to display an interface image for receiving an instruction to start each of a preparation stage of a therapy and an irradiation stage of the therapeutic beam. The input operation acquirer acquires details of an input operation performed by a user in the interface image.
