  • Publication number: 20060116833
    Abstract: A distortion compensation method includes determining an undisturbed phase for at least one of a first position indication signal and a second position indication signal. The method includes determining an undisturbed ratio that relates the amplitude of the first position indication signal at a first frequency to the amplitude of the second position indication signal at a second frequency. The method also includes determining a disturbed amplitude of the position indication signal and adjusting a position indication based on the disturbed amplitude and phase, the undisturbed amplitude ratio, and the undisturbed phase. The method further comprises determining a relationship between the eddy current phase of the first position indication signal and the second position indication signal.

  • Publication number: 20050049820
    Abstract: A system for determining the position, orientation and system gain factor of a probe includes a plurality of magnetic field sources and at least one magnetic field sensor, such that a combination of a magnetic field sensor and a magnetic field source generates a unique measured magnetic field value. The system includes a probe whose gain, position, and orientation affect these unique measured magnetic field values. A processor is configured to receive and iteratively process these unique measured magnetic field values to determine a system gain factor indicative of the gain of the probe and a plurality of location factors indicative of the position and orientation of the probe. The number of unique measured magnetic field values generated must be at least equal to the sum of the number of gain and location factors calculated.

  • Patent number: 6288785
    Abstract: A system for determining spatial position and/or orientation of one or more objects. The system includes an optical subsystem and a non-optical subsystem. The optical subsystem includes optical subsystem light sources mounted to one or more of the objects and an optical subsystem sensor adapted to detect energy from the optical subsystem light sources. The optical subsystem has an optical subsystem coordinate system in a fixed relationship with the optical subsystem sensor. The optical subsystem sensor produces position and/or orientation signals relative to the optical subsystem coordinate system in response to optical subsystem light source detected energy. The non-optical subsystem has a non-optical coordinate system and is adapted to produce position and/or orientation signals of one or more of the objects relative to the non-optical subsystem coordinate system.
