  • System and method for measuring position and orientation using distortion-compensated magnetic fields
    Patent number: 7788060
    Abstract: An electromagnetic tracking system and a distortion compensation method that utilize a lead-lag network model to compensate for position and orientation distortion caused by eddy currents formed in one more conductive distorters located within a tracking environment during electromagnetic tracking of one or more objects. The method is adaptive relative to the amount of distortion cause by the conductive distorters.
