Methods and systems for processing and/or superimposing a medical image of an anatomical body (e.g., a heart) with graphical information are provided. Reference elements and/or reference catheter are placed in contact with the anatomical body. A physical structure within a navigational coordinate system is located using the reference elements and/or reference catheter.
