Navigation system, medical system, navigation method, and use

Abstract

A navigation system for tracking a medical instrument relative to a patient includes a first navigation camera configured to capture a current position and/or orientation of the medical instrument in the visible spectrum, a second navigation camera configured to capture a current position and/or orientation of the patient in the visible spectrum, and a control unit configured to determine a current relative position and/or orientation of the medical instrument to the patient from the current position and/or orientation of the medical instrument captured by the first navigation camera and the current position and/or orientation of the patient captured by the second navigation camera. The navigation system can be incorporated into a medical system that includes a patient tracker, and can be used in a navigation method.
