Method For Determining And Ordering K-Space Views And Diffusion Weighting Directions

View page
US Patent:
8482284, Jul 9, 2013
Filed:
Jul 1, 2011
Appl. No.:
13/175059
Inventors:
Cheng Guan Koay - Madison WI, US
Samuel Anthony Hurley - Madison WI, US
Assignee:
Wisconsin Alumni Research Foundation - Madison WI
International Classification:
G01V 3/00
US Classification:
324309, 324307
Abstract:
A system and method for determining and ordering magnetic resonance imaging (MRI) acquisition parameters, such as k-space views or diffusion-weighting gradient directions, are provided. The MRI acquisition parameters are defined by generated points that are uniformly distributed on the surface of a sphere. These points may also be antipodally symmetric. The points are ordered by minimizing the electrostatic potential energy of different configurations of the points.

US Patent:
20090118608, May 7, 2009
Filed:
Nov 3, 2008
Appl. No.:
12/263569
Inventors:
Cheng Guan Koay - Rockville MD, US
Assignee:
The Government of the United States of America, represented by The Secretary, DHHS - Rockville MD
International Classification:
A61B 5/055
US Classification:
600410
Abstract:
A magnetic resonance imaging scanner acquires diffusion-weighted imaging data. A reconstruction engine reconstructs the acquired diffusion-weighted imaging data into diffusion-weighted image representations. A diffusion tensor engine constructs a diffusion tensor map of an area of an interest of a subject. An eigenvalue/eigenvector ordering engine obtains and orders eigenvectors and eigenvalues at each voxel. A covariance matrix determining engine constructs a covariance matrix of a major eigenvector of each voxel. A first normalized measure determining engine computes a first normalized measure. A second normalized measure determining engine computes a second normalized measure. A rendering engine generates a human-viewable display of an image representation.

System And Method For Determining K-Space Views And Diffusion Weighting Directions Using Centroidal Voronoi Tessellations

View page
US Patent:
20140253118, Sep 11, 2014
Filed:
Mar 11, 2013
Appl. No.:
13/792663
Inventors:
- Madison WI, US
Cheng Guan Koay - Madison WI, US
Assignee:
WISCONSIN ALUMNI RESEARCH FOUNDATION - Madison WI
International Classification:
G01R 33/48
US Classification:
324309
Abstract:
Described here are a system and method for generating uniform antipodally symmetric point sets that define diffusion-weighting directions or three-dimensional radial k-space trajectories for magnetic resonance imaging. The point sets are generated robustly and efficiently using a constrained centroidal Voronoi tessellation endowed with a pseudometric. This pseudometric is derived from a measure of the electrostatic energy of points distributed on a hemispherical surface.
