Abstract

A navigation system for navigating within a magnetic field, including a catheter with a head that is moved through the magnetic field by moving a handle of the catheter; the head includes one or more pairs of magnetic sensors; wherein the magnetic sensors are solid-state sensors that measure an electrical signal indicating a three dimensional intensity of the magnetic field at the location of the magnetic sensor; wherein each pair of magnetic sensors are rigidly connected together with a fixed displacement; and wherein the measurements of the magnetic sensors of each pair are processed together with details of the fixed displacement between the magnetic sensors of the pair to determine the location and the angular orientation of the pair of magnetic sensors.
