A robust, automatic volume registration process based on intensity gradients successfully performs registrations under conditions of unrelated intervolume voxel intensities, significant object displacements and/or significant amounts of missing data. The process allows a user to visualize the registration convergence, clearly illustrating any source of registration errors. The process includes steps of matching, based on iteratively finding a correspondence of the closest voxels containing a high three-dimensional (3D) intensity gradient magnitude. The process is a powerful method of sequence-independent MR volume registration which is simple to both use and understand. |
