Abstract

A method for registering an anatomical structure using at least one marker attached to the structure includes: obtaining a three-dimensional model of the structure via an imaging method; obtaining at least two two-dimensional recordings of the structure from different angles; and ascertaining a spatial position and location of the three-dimensional model or a position and location of the three-dimensional model in a patient coordinate system based on a matching method that uses the position of the at least one marker in the at least two two-dimensional mappings such that the three-dimensional model of the structure matches the structure.
