Abstract
A method for atlas-based segmentation is provided where a patient image is rigidly registered with each of a plurality of atlas images. Based on the rigid registration results, which indicate a degree of similarity for each atlas, an atlas image is selected for deformable registration where the rigid registration result is used as initialization. Regions of interest are segmented in the patient image using the results of the deformable registration.
