Claim Text:
1. A system for image registration, comprising: an image feature detection module configured to identify internal landmarks of a first image; an image registration and transformation module configured to compute a registration transformation, using a processor, to register a second image with the first image based on surface landmarks to result in a registered image; and a landmark identification module configured to overlay the internal landmarks onto the second image using the registration transformation, encompass the overlaid landmarks within a virtual object to identify corresponding landmark pairs in the registered image, and register the second image with the first image using the registered image with the identified landmarks; wherein the landmark identification module is further configured to register the second image with the first image using the registered image with the identified landmarks by transforming the identified landmarks in the registered image to the second image using the registration transformation; and wherein the landmark identification module is further configured to register the second image with the first image using the registered image with the identified landmarks by non-rigidly registering the second image with the first image.
