MEDICAL IMAGE ANALYSIS SYSTEM FOR ANATOMICAL IMAGES SUBJECT TO DEFORMATION AND RELATED METHODS
First Claim
1. A medical image analysis system for first and second anatomical image data of a same body area and subject to deformation, the first and second anatomical image data comprising respective first and second sets of voxels, the medical image analysis system comprising:
- a memory; and
a processor cooperating with said memory and configured togenerate a respective reach array for each voxel of the second anatomical image data, each reach array comprising a subset of contiguous voxels,generate a cost array for each reach array, each cost array based upon probabilities of voxels of the reach array matching voxels of the first anatomical image data, andsolve each cost array using belief propagation to thereby generate a deformation vector array between the first and second anatomical image data.

Abstract
A medical image analysis system is for first and second anatomical image data of a same body area and subject to deformation. The first and second anatomical image data includes respective first and second sets of voxels. The medical image analysis system includes a processor cooperating with a memory to generate a respective reach array for each voxel of the second anatomical image data, with each reach array being a subset of contiguous voxels. The processor also generates a cost array for each reach array, with each cost array based upon probabilities of voxels of the reach array matching voxels of the first anatomical image data. The processor may also solve each cost array using belief propagation to thereby generate a deformation vector array between the first and second anatomical image data.
