Em fingerprinting for distortion compensation tracking, error correction and detection

A system for using an electromagnetic (EM) tracking system, consider an electromagnetic (EM) comprises a distortion sensor array configured to sense EM energy in the target volume (144). EM sensing correction module (140) is configured to analyze data from the sensor array to detect the target volume of the biological EM distorted lead. The EM sensing distortion correction module is further configured to compare the fingerprint stored in a database (142) in order to identify the source of distortion.
