Patent number: 10213171Abstract: An X-ray photography device capable of visualizing the operating state or position of a support unit in an image system during examinations with memory switches and enhancing the operability of the memory switches is provided. When a plurality of memory switches 30a-30i is operated, target rotation information corresponding to the memory switches are read from a target rotation information memory unit 40, and a C-arm is controlled to rotate, so as to make actual rotation information consistent with the target rotation information. The memory switches 30a-30i are respectively arranged in association with rotation directions and rotation angles to designate specific storage areas in the target rotation information memory unit 40 corresponding to the directions and angles. During the rotation control or when the actual rotation information is consistent with the target rotation information, the corresponding display lamp (one of display lamps 31a-31i) of the operated memory switch is turned on.Type: GrantFiled: February 6, 2006Date of Patent: February 26, 2019Assignee: SHIMADZU CORPORATIONInventors: Katsuhiro Masuo, Mitsuru Umeda, Daisuke Murakami

Publication number: 20130028388Abstract: When a multi-system setting command switch, targeted rotating position information switches, and a command executing switch are pressed down, a CPU reads out a path of frontal and lateral systems from a current position to a setting position from a setting position information memory, and reads out rotation direction and angle from a targeted position information memory. The CPU moves the frontal and lateral systems horizontally along the read-out path until the commanded setting position information conforms to detected actual position information. When the setting position information conforms to the actual position information, the frontal and lateral systems are rotated successively until the commanded rotation direction and angle conform to the detected actual position information. Thereby a fluoroscopic X-ray system can be moved smoothly from a standby position via the setting position to a targeted rotating position.Type: ApplicationFiled: March 2, 2011Publication date: January 31, 2013Applicant: SHIMADZU CORPORATIONInventors: Koki Yoshida, Yoshihide Magari, Mitsuru Umeda

Patent number: 7012990Abstract: A switching mechanism is configured such that a lower limb radiographic filter 11a is moved inside a radiation field of the X-rays that is an opening portion of an X-ray movable restriction only when radiographing a region of a subject from the groin to the toe, or the filter is moved outside the radiation field when radiographing the lumbar region of the subject. With this switching mechanism thus constituted, it is possible to lighten a burden on the operator, and realize the X-ray radiographic apparatus having high universality.Type: GrantFiled: January 18, 2005Date of Patent: March 14, 2006Assignee: Shimadzu CorporationInventors: Kouji Akutsu, Wataru Miyamoto, Masayuki Yasumi, Tetsu Nakayama, Isao Nakata, Mitsuru Umeda
