Contrast Enhanced Mra With Highly Constrained Backprojection Reconstruction Using Phase Contrast Composite Image
US Patent:
7991452, Aug 2, 2011
Filed:
Dec 28, 2007
Appl. No.:
11/966237
Inventors:
Charles A. Mistretta - Madison WI, US
Julia Velikina - Madison WI, US
Kevin Michael Johnson - Madison WI, US
Thomas M. Grist - Madison WI, US

Assignee:
Wisconsin Alumni Research Foundation - Madison WI
International Classification:
A61B 5/055
US Classification:
600420, 600410, 600431, 382128, 382130
Abstract:
Mask projection views are obtained prior to the arrival of a contrast agent during a dynamic contrast enhanced MRA study. After the arrival of the contrast agent, a set of undersampled contrast enhanced projection views are obtained for each of a plurality of time frames. Corresponding mask projection views are subtracted from the contrast enhanced projection views to provide sparse contrast enhanced projection view sets. A phase contrast scan of a region of interest is performed prior to or after the arrival of the contrast agent. The phase contrast image is used as a composite image in a HYPR reconstruction of the sparse projection view sets to produce first pass contrast enhanced images. Iterative HYPR reconstructions can also be performed to remove venous information from the reconstructed images.
Device To Facilitate Controlled Rotation Of The Cervical Spine
US Patent:
7430773, Oct 7, 2008
Filed:
Sep 20, 2005
Appl. No.:
11/231011
Inventors:
Micah B. Brown - Westerville OH, US
Jon A. Cappel - Monroe WI, US

Assignee:
Wisconsin Alumni Research Foundation - Madison WI
International Classification:
A61G 13/12
US Classification:
5601, 5622, 5637
Abstract:
A device for controlled orientation of a person's cervical spine that is compatible with medical imaging machines. The device is capable of rotation about the axis of a patient's spinal column independent of, or in addition to, flexion/extension of a patient's spinal column. The device may incorporate locking mechanisms to secure rotational orientation and may include quantitative indicators of the degree of rotation.
Localized And Highly Constrained Image Reconstruction Method
US Patent:
8170315, May 1, 2012
Filed:
Feb 15, 2008
Appl. No.:
12/032240
Inventors:
Charles A. Mistretta - Madison WI, US
Julia Velikina - Madison WI, US
Kevin Michael Johnson - Madison WI, US
Julia Velikina - Madison WI, US
Kevin Michael Johnson - Madison WI, US
Assignee:
Wisconsin Alumni Research Foundation - Madison WI
International Classification:
G06K 9/00
US Classification:
382131
Abstract:
An image reconstruction method includes reconstructing a composite image of a subject using a conventional reconstruction method. The composite image employs the best information available regarding the subject of the scan and this information is used to constrain the reconstruction of a highly undersampled image frames or improve the SNR of image frames. A blurred and normalized weighting image is produced from image frame data, and this normalized weighting image is multiplied by the composite image.
Method For Magnitude Constrained Phase Contrast Magnetic Resonance Imaging
US Patent:
8148984, Apr 3, 2012
Filed:
Oct 5, 2009
Appl. No.:
12/573508
Inventors:
Kevin M Johnson - Madison WI, US
Alexey A Samsonov - Madison WI, US
Alexey A Samsonov - Madison WI, US
Assignee:
Wisconsin Alumni Research Foundation - Madison WI
International Classification:
G01V 3/00
US Classification:
324309
Abstract:
A method for magnitude constrained phase contrast magnetic resonance imaging (MRI) is provided. The method utilizes an assumption that the image magnitude is shared across a series of images reconstructed from a set of phase contrast enhanced k-space data. In this manner, one common magnitude image and a plurality of phase images are reconstructed substantially contemporaneously from the acquired image data. The method is further applicable to other phase contrast MRI methods, such as phase contract velocimetry. Moreover, simultaneous phase contrast velocimetry and chemical shift imaging, in which water and fat signal separation is achieved, is provided.
