Abstract
A medical system for locating a catheter distal tip within a body using a plurality electrical position sensors and a magnetic position sensor in conjunction with an acceleration sensor or rotational encoder. The system locates the catheter by using signals from the acceleration sensor or rotational encoder and magnetic sensors to compensate for positioning errors associated with electric positioning sensors.
