1. A method for local error compensation of metal distortions in using an Electromagnetic Tracking System (EMTS) comprising:

  • generating an electromagnetic field from at least one electromagnetic field generator;

    monitoring a medical device having at least one electromagnetic sensor coil moving through an anatomy;

    monitoring position readings from an error correction tool able to monitor metal distortions wherein said error correction tool is situated within proximity of said medical device comprising at least three electromagnetic sensors arranged in a known and fixed configuration;

    deriving a correction function from said position readings and electromagnetic sensors;

    applying said corrective function to said medical device monitoring to compensate for said metal distortion.
