20130131507, May 23, 2013

Filed:

Nov 23, 2011

Appl. No.:

13/304103

Inventors:

Bennett W. Jackson - Minneapolis MN, US
Stefan E. Atev - Minneapolis MN, US

International Classification:

A61B 6/03

US Classification:

600431

Abstract:

A computing system and method for generating, displaying and manipulating synthetic 2D and 3D brain tissue viability images and associated metrics from multiple perfusion maps derived from CT or other imaging system input image datasets. Stored linguistic tissue classification rules characterizing infarct, ischemic and/or normal or other tissue classes as a function of one or more perfusion parameters are used. The perfusion maps are normalized to normal brain tissue regions. Elements of the input image dataset are classified into one of the tissue classes as a function of the normalized perfusion maps and the classification rules. The classification includes ranking each of the plurality of tissue classes for elements of the input image dataset, and assigning one of the classes to elements of the dataset as a function of the ranks.
