1. A method for magnetically tracking a device of interest, the method comprises:

  • generating a plurality of pre-determined multi-frequency signals;

    transmitting a plurality of magnetic fields from a transmitter circuit based on the corresponding pre-determined multi-frequency signals, the magnetic fields propagating through an area of examination encompassing a device of interest and a magnetic sensor coupled to the device of interest;

    generating a sensor signal at the magnetic sensor indicative of field strength of the magnetic fields transmitted by the transmitter circuit; and

    determining a position of the magnetic sensor relative to the transmitter circuit based on the multi-frequency signals and the sensor signal.
