Rapid convolution based large deformation image matching via landmark and volume imagery
First Claim
Patent Images
1. A method for registering images comprising:
- selecting a template image;
selecting a target image, wherein at least one image point contained in said target image corresponds to at least one image point in said template image;
defining a distance function that expresses a distance between said template image and target image; and
registering said template image and said target image as a function of the distance using a large deformation registration function that incorporates said at least one image point contained in said target image and said at least one image point in said template image.

Abstract
An apparatus and method for image registration of a template image with a target image with large deformation. The apparatus and method involve computing a large deformation transform based on landmark manifolds, image data or both. The apparatus and method are capable of registering images with a small number of landmark points. Registering the images is accomplished by applying the large deformation transform.
