Abstract
A system and method for navigating a medical device within a body are provided. The system includes an electronic control unit configured to determine operating positions for electrical and magnetic position sensors on the medical device within corresponding first and second coordinate systems. The first and second coordinate systems are defined by an electric field based positioning system and a magnetic field based positioning system, respectively. The magnetic position sensor is disposed proximate the electrical position sensor. The ECU is further configured to apply a mapping function correlating the operating positions which generates a mapped position for the magnetic position sensor in the first coordinate system responsive to the operating position of the magnetic position sensor in the second coordinate system. The ECU determines an adjusted operating position for the electrical position sensor in the first coordinate system responsive to the mapped position of the magnetic position sensor.
