Publication number: 20090252285Abstract: A CT scanner includes a first X-ray beam source, and a second X-ray beam source. With such an apparatus, first source is used to monitor buildup of an injected contrast agent in a selected region of interest relative to a patient and at least the second source is used to perform diagnostic scanning when the buildup of the contrast agent reaches a desired level.Type: ApplicationFiled: April 6, 2009Publication date: October 8, 2009Applicant: Arineta Ltd.Inventors: Olga Shapiro, David Ruimi, Rafi Brada, Ehud Dafni

Patent number: 7424090Abstract: The present invention is a directed method and apparatus for collimating a radiation beam such that the full intensity of the radiation beam does not impinge detectors of a radiation detector assembly that are particularly susceptible to saturation or over-ranging. This collimation can be dynamically adjusted on a per view basis using empirical or scout scan data.Type: GrantFiled: May 8, 2007Date of Patent: September 9, 2008Assignee: General Electric CompanyInventors: Jerome Stephen Arenson, David Ruimi, Oded Meirav, Robert Harry Armstrong

Patent number: 7382853Abstract: An adaptive CT data acquisition system and technique is presented whereby radiation emitted for CT data acquisition is dynamically controlled to limit exposure to those detectors of a CT detector assembly that may be particularly susceptible to saturation during a given data acquisition. The data acquisition technique recognizes that for a given subject size and position that pre-subject filtering and collimating of a radiation beam may be insufficient to completely prevent detector saturation. Therefore, the present invention includes implementation of a number of CT data correction techniques for correcting otherwise unusable data of a saturated CT detector. These data correction techniques include a nearest neighbor correction, off-centered phantom correction, off-centered synthetic data correction, scout data correction, planar radiogram correction, and a number of others.Type: GrantFiled: November 24, 2004Date of Patent: June 3, 2008Assignee: General Electric CompanyInventors: Jerome S. Arenson, David Ruimi, Lev Greenberg, Yanfeng Du

Patent number: 7336769Abstract: The invention is directed to an x-ray flux management device that adaptively attenuates an x-ray beam to limit the incident flux reaching a subject and radiographic detectors in potentially high-flux areas while not affecting the incident flux and detector measurements in low-flux regions. While the invention is particularly well-suited for CT, the invention is also applicable with other x-ray imaging systems. In addition to reducing the required detector system dynamic range, the present invention provides an added advantage of reducing radiation dose.Type: GrantFiled: January 11, 2007Date of Patent: February 26, 2008Assignee: General Electric CompanyInventors: Jerome Stephen Arenson, David Ruimi, Oded Meirav, Robert Harry Armstrong
