System and method for segmenting tissue types in dual-echo magnetic resonance images

Abstract

A system and method is provided for classifying voxels of first and second images generated using first and second echoes of a dual MRI scan, the first and second echoes corresponding to respective first and second sets of image acquisition parameters. The method includes the steps of providing for accessing first image data corresponding to the first image including an array of voxels, the first image data including a first associated parameter value Sfor a parameter of the imaging associated with respective voxels of the array of voxels; providing for accessing second image data corresponding to the second image including the array of voxels, the second image data including a second associated parameter value Sfor the parameter of the imaging associated with respective voxels of the array of voxels; and providing for determining R and θ values associated with respective voxels of the array of voxels, wherein for each respective voxel R substantially equals (S+S), and θ substantially equals arctan(S/S) for Sand Sassociated with the respective voxel.
