Claim 0:
1. A computer-implemented method for determining a state from medical images, the method comprising:
providing to a processor a test image dataset from a subject and a library of reference image datasets from subjects, each one of said reference image datasets defining one of a plurality of states related to at least one of disease, function and probability of developing a disease, said library of reference image datasets from subjects representing a number of subjects in each of said plurality of states;
performing registration of said test image dataset and said library of reference image datasets;
selecting a region of interest of said test image dataset and patch dimensions;
for each pixel or voxel in said region of interest of said test image dataset:
defining a test patch of said patch dimensions centered on said pixel or voxel in said region of interest;
for each reference image dataset of said library of reference image datasets:
defining a reference patch of said patch dimensions centered on said pixel or voxel of said reference image dataset;
calculating a similarity value between said test patch and said reference patch;
storing said similarity value for each one of said plurality of states for one of said pixels or voxels of said region of interest of said test image dataset;

determine, for said pixel or voxel in said region of interest of said test image dataset, a weight for each one of said plurality of disease states using said similarity values and the corresponding disease state of said reference image dataset;

evaluating said weight for each one of said plurality of states for all of said pixels or voxels in said region of interest of said test image dataset to determine a likelihood of said plurality of states associated with said test image dataset.
