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: 10448915Abstract: A method for characterizing anatomical features includes receiving scanned data and image data corresponding to a subject. The scanned data comprises sinogram data. The method further includes identifying a first region in an image of the image data corresponding to a region of interest. The method also includes determining a second region in the scanned data. The second region corresponds to the first region. The method further includes identifying a sinogram trace corresponding to the region of interest. The sinogram trace comprises sinogram data present within the second region. The method includes determining a data feature of the subject based on the sinogram trace and a deep learning network. The method also includes determining a diagnostic condition corresponding to a medical condition of the subject based on the data feature.Type: GrantFiled: June 27, 2017Date of Patent: October 22, 2019Assignee: General Electric CompanyInventors: Bruno Kristiaan Bernard De Man, Jed Douglas Pack, Eri Haneda, Sathish Ramani, Jiang Hsieh, James Vradenburg Miller, Peter Michael Edic

Patent number: 9824468Abstract: A computationally efficient dictionary learning-based term is employed in an iterative reconstruction framework to keep more spatial information than two-dimensional dictionary learning and require less computational cost than three-dimensional dictionary learning. In one such implementation, a non-local regularization algorithm is employed in an MBIR context (such as in a low dose CT image reconstruction context) based on dictionary learning in which dictionaries from different directions (e.g., x,y-plane, y,z-plane, x,z-plane) are employed and the sparse coefficients calculated accordingly. In this manner, spatial information from all three directions is retained and computational cost is constrained.Type: GrantFiled: December 31, 2015Date of Patent: November 21, 2017Assignee: General Electric CompanyInventors: Jiajia Luo, Bruno Kristiaan Bernard De Man, Ali Can, Eri Haneda

Publication number: 20170221235Abstract: The present approach relates to the use of a database (i.e., a dictionary) of image patterns to be avoided or de-emphasized during an image reconstruction process, such as an iterative image reconstruction process. Such a dictionary may be characterized as a negative or “bad” dictionary. The negative dictionary may be used to constrain an image reconstruction process to avoid or minimize the presence of the patterns present in the negative dictionary.Type: ApplicationFiled: February 1, 2016Publication date: August 3, 2017Inventors: Bruno Kristiaan Bernard De Man, Lin Fu, Jiajia Luo, Eri Haneda, Sathish Ramani

Publication number: 20170039735Abstract: Approaches related to performing calibration of a CT scanner or of processes (e.g., correction and/or reconstruction) performed on acquired CT scan data are described. In certain described approaches, calibration is attained without performing a calibration scan using a dedicated calibration phantom. In certain embodiments, calibration is performed using a feature intrinsic to the imaged object, such as a jacket disposed about a drilled core sample.Type: ApplicationFiled: August 6, 2015Publication date: February 9, 2017Inventors: Ali Can, Bruno Kristiaan Bernard De Man, Jed Douglas Pack, John Christopher Boot, Eri Haneda

Patent number: 8730329Abstract: This disclosure describes techniques for initially calibrating an image capture device. According to one aspect, the calibration includes calibrating parameters of an image filter for resolving the captured image. The method includes receiving a captured image of a test target and resolving the captured image using a set of initial parameters. A sharpness index of the resolved image is determined without matching the captured image to the test target. The sharpness index is used to minimize a cost function for determining parameters for use by the image capture device.Type: GrantFiled: July 11, 2011Date of Patent: May 20, 2014Assignee: Qualcomm, IncorporatedInventors: Xiaoyun Jiang, Eri Haneda
