Abstract: A method of image processing, comprising obtaining a three-dimensional standard animal body image having three intersecting two-dimensional planes and comprising an anatomical landmark; obtaining a three-dimensional radiographic image of a patient animal having a corresponding anatomical landmark; and comparing the standard animal body image with the radiographic image by: identifying the location of the anatomical landmark on one two-dimensional plane in the standard animal body image; automatically propagating the identified location of the anatomical landmark to the other two two-dimensional planes in the standard animal body image; identifying the location of the anatomical landmark in the radiographic image of the patient animal; and morphing the radiographic image of the patient animal to the standard animal body image by deforming the radiographic image of the patient animal to cause the locations of the landmark on the radiographic image and the standard animal body image to overlap.
