Patent number: 9103898Abstract: A method includes the acts of acquiring a blade of k-space calibration data; acquiring a set of T1-weighted k-space imaging data, the set of T1-weighted k-space imaging data having blades of undersampled k-space data rotated about a section of k-space. Each blade of undersampled k-space data includes first data points having acquired data and second data points that are missing data. The method also includes generating a set of reconstruction weights for the blades of undersampled k-space data using the blade of k-space calibration data; synthesizing k-space data for at least a portion of the second data points using the set of reconstruction weights; and generating a T1-weighted image using the T1-weighted k-space imaging data and the synthesized k-space data.Type: GrantFiled: April 18, 2012Date of Patent: August 11, 2015Assignee: GENERAL ELECTRIC COMPANYInventors: James Hartman Holmes, Jean Helen Brittain, Reed Frederick Busse, Ajeetkumar Gaddipati, Xiaoli Zhao, Philip James Beatty, Zhiqiang Li, Howard Andrew Rowley

Patent number: 7411397Abstract: The present invention is directed to slice selective magnetization preparation for moving table MRI. The present invention includes a method of magnetization preparation that takes into account patient movement or translation during the imaging process. The present invention adjusts or modifies the frequency at which magnetization preparation pulses are applied to offset the preparation pulse in space. This allows preparation pulses to be interleaved with imaging and enables magnetization preparation without sacrificing other imaging variables or parameters defined for the particular MR study. As such, contrast within a reconstructed image is improved.Type: GrantFiled: January 30, 2007Date of Patent: August 12, 2008Assignee: General Electric CompanyInventors: Ajit Shankaranarayanan, Jean Helen Brittain

Patent number: 6891374Abstract: A system and method are disclosed using continuous table motion while acquiring data to reconstruct MR images across a large FOV without significant slab-boundary artifacts that reduces acquisition time. At each table position, full z-encoding data are acquired for a subset of the transverse k-space data. The table is moved through a number of positions over the desired FOV and MR data are acquired over the plurality of table positions. Since full z-data are acquired for each slab, the data can be Fourier transformed in z, interpolated, sorted, and aligned to match anatomic z locations. The fully sampled and aligned data is then Fourier transformed in remaining dimension(s) to reconstruct the final image that is free of slab-boundary artifacts.Type: GrantFiled: December 30, 2003Date of Patent: May 10, 2005Assignee: General Electric CompanyInventor: Jean Helen Brittain

Patent number: 6801034Abstract: A system and method are disclosed using incremental table motion and partial data acquisition for increased volume coverage to reconstruct MR images across a large FOV without significant slab-boundary artifacts. At each table position, full z-encoding data are acquired for a subset of the kx-ky data. The table is stepped through a number of positions over the desired FOV and MR data are acquired over the plurality of table increments. Since full z-data are acquired for each slab, the data can be Fourier transformed in z, sorted, and then aligned to match anatomic z locations. The fully sampled and aligned data is then Fourier transformed in x and y to reconstruct the final image that is free of slab-boundary artifacts.Type: GrantFiled: March 30, 2001Date of Patent: October 5, 2004Assignee: General Electric CompanyInventors: Jean Helen Brittain, John Mark Pauly
