Claim:
1. A computer-implemented method of image segmentation, comprising: (i) constructing articulated models including individual section images representing related anatomical regions of an object of interest, wherein the section images are acquired by a first modality and aligned with local images of the related anatomical regions acquired by a second modality, wherein the first and second modalities are different, wherein at least one of the articulated models comprises one of the local images, corresponding annotated landmarks and a corresponding one of the aligned section images; (ii) receiving first image data acquired by the first modality; (iii) aligning an anatomical region of the first image data with a corresponding one of the aligned section images; (iv) non-rigidly registering a first region of interest extracted from the corresponding aligned section image with a second region of interest extracted from the aligned anatomical region; (v) generating a segmentation mask of the anatomical region by inversely mapping the registered first region of interest to a subject space of the first image data; and repeating steps (iii), (iv) and (v) to segment another anatomical region of the first image data.
