Patent number: 11141126Abstract: 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.Type: GrantFiled: December 18, 2018Date of Patent: October 12, 2021Assignee: Toshiba Energy Systems & Solutions CorporationInventors: Shinichiro Mori, Koki Yanagawa, Ryusuke Hirai, Shinya Fukushima, Keiko Okaya

Patent number: 10940331Abstract: 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.Type: GrantFiled: December 18, 2018Date of Patent: March 9, 2021Assignee: Toshiba Energy Systems & Solutions CorporationInventors: Shinichiro Mori, Keiko Okaya, Ryusuke Hirai, Fumi Maruyama, Koki Yanagawa

Patent number: 6327510Abstract: 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.Type: GrantFiled: January 20, 1999Date of Patent: December 4, 2001Assignee: Kabushiki Kaisha ToshibaInventors: Yutaka Yoshida, Koki Yanagawa, Takuji Tahara, Shoichi Sano, Hideki Takahashi, Haruyoshi Iwase, Koji Saito, Takahiro Yamamoto
