Abstract:
1. A method for determining a characteristic axis of a body structure, comprising: comparing each of at least two two-dimensional mappings of an area of the body structure with a generic model of the area in question, said generic model containing information on the position of the characteristic axis; ascertaining a mapping protocol for mapping the generic model onto the respective mappings of the area; using the ascertained mapping protocol to map the position of the characteristic axis in the generic model onto each of the at least two two-dimensional mappings of the area of the body structure; and back-projecting the at least two two-dimensional mappings of the area of the body structure to determine a three-dimensional position of the characteristic axis, wherein back-projecting comprises reconstructing, from the at least two two-dimensional mappings, three-dimensional data corresponding to the body structure.
