Method for operating navigation system for performing medical procedure, involves determining actual relative position of primary position marker by navigation system at secondary position marker

摘要

The method involves determining an actual relative position of a primary position marker (14) by a navigation system (8) at a secondary position marker (14a), where the primary position marker is located in a fixed position relative to the secondary position marker. The actual relative position is compared with a known relative position between the primary position marker and the secondary position marker. An independent claim is also included for a device for controlling an electromagnetically operating navigation system for performing a medical procedure.
