SYSTEM AND METHOD FOR COREGISTRATION AND ANALYSIS OF NON-CONCURRENT DIFFUSE OPTICAL AND MAGNETIC RESONANCE BREAST IMAGES
First Claim
1. A method for joint analysis of non-concurrent magnetic resonance (MR) and diffuse optical tomography (DOT) images of the breast, comprising the steps of:
- providing a digitized MR breast image volume comprising a plurality of intensities corresponding to a 3-dimensional (3D) grid of voxels;
providing a digitized DOT breast dataset comprising a plurality of physiological values corresponding to a finite set of points;
segmenting said breast MR image volume to separate tumorous tissue from non-tumorous tissue;
registering said DOT breast dataset and said MR image volume; and
fusing said registered DOT and MR datasets, wherein said fused dataset is adapted for analysis.
