IMPROVING SYMMETRY IN BRAIN SCANS
First Claim
Patent Images
1. A method for reducing anatomical asymmetry in a brain scan image, comprising:
- adapting a symmetric model representing anatomical structures of a brain to the brain scan image by transforming first and second points of the symmetric model to corresponding first and second points provided on first and second hemispheres of the brain scan image; and
computing, based on the transformation, a patient-specific symmetric anatomical model of the brain.

9. A method, comprising:
-
adapting a symmetric three-dimensional model representing anatomical structures of the brain, the model corresponding to a two-dimensional brain scan image; transforming the symmetric model such that corresponding locations in first and second hemispheres thereof are symmetrical about a mid-plane; and computing corresponding first and second locations in first and second hemispheres of the brain using a transformation field. - View Dependent Claims (10, 11)
