摘要： A method for determining a characteristic axis of a body structure includes generating at least two two-dimensional recordings of an area of the body structure; comparing each of the at least two recordings of the area 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 respective generic model onto the respective recording of the area; using the ascertained mapping protocol to map the respective position of the characteristic axis in the respective generic model to obtain the respective position of the characteristic axis in the two-dimensional mapping of the body structure; and using rear projection to determine a three-dimensional position of the characteristic axis from the at least two characteristic axes in the two-dimensional mappings.
