Abstract

A system and method for determining the position of correspondence object pairs including A-objects and B-objects that represent the same objects of the same anatomical body structure in two different reference frames A and B, including: defining A-objects and B-objects that each represent different objects of the body structure in their respective reference frames; determining geometric relationship data A and geometric relationship data B that describe a geometric relationship between the A-objects based on positions of the A-objects in the reference frame A and the B-objects in the B reference frame; and providing data derived or extracted from the geometric relationship data A and from the geometric relationship data B to allow a comparison of a geometric relationship between at least two A-objects to a geometric relationship between at least two B-objects.
