ABSTRACT:
A method, apparatus, and system for tracking an object within a volume, includes coupling a rotating magnetic dipole to the object, measuring the magnetic fields either remotely, on the surface of, or exterior to the volume, to produce measurements; and based on the measurements, determining the position and the orientation of the magnetic dipole, thereby to determine a position and orientation of the object.
