Patent number: 11688044Abstract: A computer-implemented method of validating motion correction of magnetic resonance (MR) images in a quantitative parametric map of a parameter is provided. The method includes receiving a series of motion corrected images of a series of MR images, wherein the series of MR images are MR images of an anatomical region at different points of time. For each pixel of a plurality of pixels in one of the series of motion corrected images, the method further includes generating a time series at the pixel based on the series of motion corrected images, fitting the time series to a model of the parameter, and estimating an indicator of goodness of fit of the time series to the model. The method also includes generating a metric indicating effectiveness of the motion correction based on estimated indicators of goodness of fit of the plurality of pixels, and validating the motion correction based on the metric.Type: GrantFiled: February 5, 2021Date of Patent: June 27, 2023Assignee: GE PRECISION HEALTHCARE LLCInventor: Gaspar Delso Gafarot

Patent number: 10677873Abstract: A system for correcting an artifact within MR data is provided. The system includes a magnet assembly and a controller in electronic communication with the magnet assembly. The controller is operative to: acquire the MR data from a subject via the magnet assembly, the MR data having a first portion and a second portion, the first portion including the artifact; and to populate the first portion of the MR data with substitute data corresponding to the second portion. The first portion corresponds to a first region of the subject, and the second portion corresponds to a second region of the subject that is anatomically symmetrical to the first region.Type: GrantFiled: August 29, 2017Date of Patent: June 9, 2020Assignee: GENERAL ELECTRIC COMPANYInventor: Gaspar Delso

Publication number: 20090149756Abstract: A method and apparatus for medical ultrasound imaging. A three dimensional image data of a whole organ is acquired at a first resolution during a cardiac cycle. A three dimensional image data of a sector of the organ is acquired at a second higher resolution during another cardiac cycle. The data are compared so as to allow registration of the sector with respect to the whole organ.Type: ApplicationFiled: June 19, 2007Publication date: June 11, 2009Applicant: KONINKLIJKE PHILIPS ELECTRONICS, N.V.Inventors: Pau Soler, Olivier Gerard, Gaspar Delso, Pascal Allain
