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.

Medical apparatus and method

A medical apparatus according to an embodiment includes an acquirer and a selector. The acquirer is configured to acquire fluoroscopic images of an object captured in time series. The selector is configured to select reference images which include fluoroscopic images corresponding to a maximum exhalation position and a maximum inhalation position of the object from the plurality of fluoroscopic images acquired by the acquirer.

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.

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. The controller is configured to cause the imager to stop performing irradiation of the electromagnetic wave and cause the acquirer to stop acquiring the fluoroscopic image, in a case where a first switch is operated, and the controller is configured to cause the imager to stop performing irradiation of the electromagnetic wave and maintain a state in which the acquirer is capable of acquiring the fluoroscopic image, in a case where a second switch is operated.

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.

A movable part tracking and treatment apparatus includes an acquisition unit adapted to acquire a three-dimensional moving image and a first projection image generation unit adapted to generate a first projection moving image. The apparatus further includes an affected part image extraction unit adapted to extract the displaced affected part area from the first projection moving image and a tracing target image extraction unit adapted to extract the displaced tracing target from the first projection moving image. The apparatus also includes a first parameter derivation unit adapted to derive a first parameter indicative of position information on a beam irradiation point and a second parameter derivation unit adapted to derive a second parameter necessary to extract the corresponding tracing target.

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.
