Medical apparatus and method
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.

7. The medical apparatus according to claim 6 ,
wherein the succeeded information includes a position of a lesion designated in three-dimensional volume data.
8. The medical apparatus according to claim 6 ,
wherein the succeeded information includes a position of a selected marker.
9. The medical apparatus according to claim 1 ,
wherein the display controller is configured to cause the display to display the irradiation permission range in a manner of being superimposed on the fluoroscopic image and changes a color of the irradiation permission range when the irradiation permission signal is output.
10. The medical apparatus according to claim 1 ,
wherein the display controller is configured to cause the display to display the irradiation permission range in a manner of being superimposed on the fluoroscopic image and changes a hue or brightness of any of an inner region or an outer region of the irradiation permission range when the irradiation permission signal is output.
