SUPERIMPOSING BRAIN ATLAS IMAGES AND BRAIN IMAGES WITH DELINEATION OF INFARCT AND PENUMBRA FOR STROKE DIAGNOSIS
First Claim
1. A method of analyzing brain images of a patient for stroke diagnosis of said patient, comprising:
- capturing a first image of the brain of said patient suitable for determining infarct regions of said brain;
capturing a second image of said brain suitable for determining penumbra regions of said brain;
determining an infarct region of said brain from said first image;
determining a penumbra region of said brain from said second image;
co-registering said first and second images to a co-ordinate system;
mapping pre-existing brain atlas images to said co-ordinate system to form patient-specific brain atlas images;
delineating said infarct region and said penumbra region of said brain on said patient-specific brain atlas images in said co-ordinate system; and
superimposing said first and second images, with said patient-specific brain atlas images.

Abstract
Brain images are processed and analyzed with the aid of a computer for stroke diagnosis or therapeutic decision making, where multiple stroke-related images are superimposed. The superimposed images include brain images that have infarct and penumbra regions, and patient-specific brain atlas images. The infarct and penumbra regions are determined and delineated on the superimposed images. Each patient-specific brain atlas image may be formed by mapping a pre-existing brain atlas to a co-ordinate system in which the brain images are co-registered. A brain atlas may depict brain structures such as anatomy structures, blood supply territories (BST), or cerebral vasculature. The superimposed images may be used to determine any overlap between a particular brain structure and the infarct and penumbra regions.
