Patent number: 11510650Abstract: According to one embodiment, an ultrasound diagnosis apparatus includes an image processing circuit and a processing circuit. The image processing circuit generates an ultrasound image. The processing circuit receives a medical image acquired by another medical image diagnosis apparatus, and aligns the ultrasound image and the medical image. The processing circuit has a function of recognizing identification information held by the medical image when the ultrasound image and the medical image are displayed side by side on a display. The processing circuit also has a function of retrieving diagnostic protocol information corresponding to the identification information and displaying it on the display, and a function of performing examinations and processes based on the diagnostic protocol information displayed.Type: GrantFiled: September 29, 2017Date of Patent: November 29, 2022Assignee: CANON MEDICAL SYSTEMS CORPORATIONInventors: Naoki Yoneyama, Takatoshi Okumura, Naoyuki Nakazawa, Masatoshi Nishino, Norihisa Kikuchi, Kazutoshi Sadamitsu

Publication number: 20170007201Abstract: An ultrasonic diagnostic apparatus according to a present embodiment includes processing circuitry. The processing circuitry is configured to extract a cardiac valve from three-dimensional images of frames generated by controlling an ultrasonic probe to perform transmission and reception of ultrasonic waves. The processing circuitry is configured to calculate, as a prolapse gap, a gap between valve leaflets of the cardiac valve in a three-dimensional image of a specific frame among the frames. The processing circuitry is configured to display the prolapse gap on a display.Type: ApplicationFiled: April 20, 2016Publication date: January 12, 2017Applicant: TOSHIBA MEDICAL SYSTEMS CORPORATIONInventors: Yutaka KOBAYASHI, Kazutoshi SADAMITSU, Jiro HIGUCHI, Masatoshi NISHINO, Norihisa KIKUCHI, Atsushi SUMI, Naoyuki NAKAZAWA, Atsushi NAKAI, Cong YAO, Naoki YONEYAMA, Kazuo TEZUKA, Yoshitaka MINE, Masami TAKAHASHI

Patent number: 5243416Abstract: Image recording method and apparatus for recording a plurality of non-synchronous image data from a plurality of imaging devices, capable of achieving a reliable image recording operation without using a plurality of time base correctors. In the apparatus, one of the non-synchronous image data from one imaging device is selectively transmitted, and a synchronous signal is extracted from that non-synchronous image data. Then, a synchronized operation command signal is obtained from an externally given operation command signal and the extracted synchronous signal, and a single time base corrector is provided for transmitting image data to be recorded in that non-synchronous image data at a predetermined recording timing, by using the synchronized operation command signal, such that the image data to be recorded transmitted by the time base corrector can be recorded.Type: GrantFiled: April 9, 1991Date of Patent: September 7, 1993Assignee: Kabushiki Kaisha ToshibaInventor: Naoyuki Nakazawa
