Patent number: 7819580Abstract: Disclosed is an arm frame structure for a radiation imaging system, comprising a first upright column, a mounting frame, and first and second collimators mounted on said first upright column, and first and second detector devices. Said first and second collimators are arranged to be symmetrical with respect to a plane therebetween to divide a ray beam emitted from a radiation source into first and second beams emitted symmetrically. Said first and second detector devices are symmetrically mounted on the mounting frame with respect to the plane P and are arranged to be far away from said first and second collimators to receive the first and second beams, respectively. This invention further provides a radiation imaging system including the arm frame structure.Type: GrantFiled: December 23, 2008Date of Patent: October 26, 2010Assignee: Nuctech Company LimitedInventors: Quanwei Song, Hui Meng

Publication number: 20100232575Abstract: An apparatus for digital radiography has a cassette adapted to obtain a digital image of a subject in response to incident radiation when receiving source power through an input power connector and adapted to provide the obtained digital image as output from a first data connector. A support tray is adapted to removably seat the cassette and has a second data connector that releasably engages with the first data connector on the cassette when the cassette is seated in the support tray. A wireless communication circuit in the support tray is energizable to transmit the digital image obtained from first data connector of the cassette to a host processor. A battery in the tray provides source power to at least the wireless communication circuit on the support tray circuitry and the input power connector of the seated cassette.Type: ApplicationFiled: March 16, 2009Publication date: September 16, 2010Inventor: John H. Hall

Patent number: 7785005Abstract: A cassette accommodating device accommodates cassettes with various sizes. Each cassette houses a rechargeable battery and a radiation detection unit that generates a radiographic image according to an amount of received radiation and each cassette is provided with a power receiving unit for recharging the rechargeable battery on at least one of two connected side faces of each cassette. The device includes a groove portion formed with a sloping face that faces one of the two connected side faces of an accommodated cassette and a bottom face that faces another of the two connected side faces of the accommodated cassette. The bottom face is inclined such that the cassette moves toward the sloping face when the cassette is loaded. A power supply unit is formed to the sloping face and/or the bottom face so as to supply power to the power receiving unit when the cassette has been accommodated.Type: GrantFiled: March 17, 2009Date of Patent: August 31, 2010Assignee: FUJIFILM CorporationInventors: Akihito Bettouyashiki, Yoshiki Takeoka, Yutaka Yoshida, Keiji Tsubota, Shoji Takahashi, Yasunori Ohta, Naoyuki Nishino

Publication number: 20100208871Abstract: A radiation detecting cassette is disposed in a desired position between a bed and a patient in an operating room. After a detector-side connector and a bed-side connector are connected to each other by a cable, an image capturing apparatus captures and records radiation image information of the patient in a radiation detector. The recorded radiation image information is transmitted from a transceiver of the bed to a console by way of wireless communications in a communication range selected by a selector of the bed, then processed by the console, and transmitted to a display device, which displays a radiation image based on the supplied radiation image information.Type: ApplicationFiled: March 25, 2010Publication date: August 19, 2010Applicant: FUJIFILM CorporationInventors: Tsuyoshi Tanabe, Eiichi Kito, Takuya Yoshimi, Takeshi Kuwabara, Kazuharu Ueta, Makoto Iriuchijima, Yasunori Ohta
