Patent number: 11684324Abstract: A medical image diagnosis apparatus according to an embodiment of the present disclosure includes: a gantry, one or more columns, a processing circuitry, and, and a supporting and moving mechanism. The gantry includes an imaging system related to imaging a patient. The one or more columns are each configured to support the gantry so as to be movable in a vertical direction. The processing circuitry generates an image on the basis of an output from the imaging system. The supporting and moving mechanism is configured to support the patient from underneath, while being installed so as to be movable in a direction intersecting the moving direction of the gantry. The processing circuitry controls the moving of the supporting and moving mechanism.Type: GrantFiled: July 14, 2021Date of Patent: June 27, 2023Assignee: CANON MEDICAL SYSTEMS CORPORATIONInventors: Shouichi Nakagawa, Yohei Matsuzawa

Publication number: 20230073617Abstract: An X-ray computed tomography apparatus includes a gantry, a support member, a mount frame, and a support stand. The gantry includes an imaging system to image a subject. The support member supports a support plate that supports the subject in imaging. The support member and the gantry are mounted on a mount frame such that a relative positional relationship between the support member and the gantry is changeable in a longitudinal direction of the support plate. The support stand supports the mount frame in a manner that the mount frame is changeable in posture at least in-between a vertical direction and a horizontal direction.Type: ApplicationFiled: August 5, 2022Publication date: March 9, 2023Applicant: CANON MEDICAL SYSTEMS CORPORATIONInventors: Kei AOKI, Yohei MATSUZAWA

Patent number: 10827988Abstract: An X-ray computed-tomography (CT) apparatus according to an embodiment includes an X-ray tube, a detector, a table top, and processing circuitry. The X-ray tube generates an X-ray. The detector detects the X-ray. On the table top, a subject is placed. The processing circuitry controls a moving mechanism to move the table top in a longitudinal direction. The processing circuitry displays information indicating magnitude of a vibration that occurs, when each position in the longitudinal direction on the table top is moved to a position intersecting a path of the X-ray, at the position.Type: GrantFiled: May 8, 2017Date of Patent: November 10, 2020Assignee: CANON MEDICAL SYSTEMS CORPORATIONInventors: Ryuichi Teramoto, Ryo Furukawa, Kiminori Toya, Yohei Matsuzawa, Masayuki Wakahara, Keisuke Oishi

Patent number: 10595811Abstract: According to one embodiment, an X-ray computed tomography apparatus includes a gantry main body, a base, a first support frame, a second support frame and gantry control circuitry. The gantry control circuitry controls a tilt of the gantry main body, a movement of the table top by the first support frame, and a movement of the first support frame by the second support frame. The gantry control circuitry executes switching between a first tilt mode in which the gantry main body is tiltable in a first angle range and a second tilt mode in which the gantry main body is tiltable in a second angle range in which a tilt angle is greater than in the first angle range.Type: GrantFiled: December 27, 2017Date of Patent: March 24, 2020Assignee: Canon Medical Systems CorporationInventors: Asako Sato, Yohei Matsuzawa, Keisuke Oishi

Patent number: 10548547Abstract: The rigidity of a gantry is efficiently increased in a limited space. A gantry rotating unit has a structure on which an X-ray tube and an X-ray detector can be mounted. A main frame supports the gantry rotating unit so as to allow it to rotate around a rotation axis. A base stand supports the main frame from the floor surface. Gantry arms are coupled to one of half portions of the main frame which are one of half portions divided by a horizontal axis and the base stand. Reinforcing frames are coupled to the other of the half portions of the main frame and the gantry arms.Type: GrantFiled: June 4, 2015Date of Patent: February 4, 2020Assignee: Canon Medical Systems CorporationInventor: Yohei Matsuzawa
