Patent number: 10736594Abstract: In accordance with the present disclosure, the present technique finds a diagnostic scan timing for a non-static object (e.g., a heart or other dynamic object undergoing motion) from raw scan data, as opposed to reconstructed image data. To find the scan timing, a monitoring scan of a patient's heart is performed. In the monitoring scan, the patient dose may be limited or minimized. As the projection data is acquired during such a monitoring scan, the projection data may be subjected to sinogram analysis in a concurrent or real-time manner to determine when to start (or trigger) the diagnostic scan.Type: GrantFiled: November 26, 2018Date of Patent: August 11, 2020Assignee: GENERAL ELECTRIC COMPANYInventors: Bruno Kristiaan Bernard De Man, Eri Haneda, Jed Douglas Pack, Bernhard Erich Hermann Claus

Patent number: 10674986Abstract: The present approach provides a non-invasive methodology for estimation of coronary flow and/or fractional flow reserve. In certain implementations, various approaches for personalizing blood flow models of the coronary vasculature are described. The described personalization approaches involve patient-specific measurements and do not assume or rely on the resting coronary flow being proportional to myocardial mass. Consequently, there are fewer limitations in using these approaches to obtain coronary flow and/or fractional flow reserve estimates non-invasively.Type: GrantFiled: May 13, 2016Date of Patent: June 9, 2020Assignee: GENERAL ELECTRIC COMPANYInventors: Prem Venugopal, Jed Douglas Pack, Bruno Kristiaan Bernard De Man, Peter Michael Edic, Jiang Hsieh
