  • Patent number: 11141126
    Abstract: A medical apparatus includes an acquirer, an associator, and a display controller. The acquirer acquires information indicating a respiratory waveform of an object and acquires fluoroscopic images of the object captured in time series. The associator associates a tracking value which fluctuates according to a respiratory phase of the object, based on the time-series fluoroscopic images. The display controller causes a display to display the respiratory waveform and a waveform of the tracking value in a comparable form.

  • 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: 10835762
    Abstract: A medical apparatus according to an embodiment includes an acquirer, an identifier, and a controller. The acquirer acquires a fluoroscopic image of an 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 controller outputs an irradiation permission signal to a therapeutic device which irradiates the object with a therapeutic beam in a case where the target position identified by the identifier is settled within an irradiation permission range.

  • 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.

  • Patent number: 6327510
    Abstract: In a plant supervisory system, many computers (functional servers) that distributively perform functions are connected through two types of transmission paths (such as a control bus and an information bus). The control bus is used to transmit periodic data such as process data. Event data is transmitted through the information bus. Thus, many computers can be connected. In addition, the latest value of process data can be referenced by each computer.
