Claim 0:
1. A method of compensating for electromagnetic (EM) distortion, comprising:
determining a reference position of a distal end of an instrument at a first time based on EM location data, the instrument comprising one or more EM sensors configured to generate the EM location data indicative of a position of the distal end of the instrument;
determining that the distal end of the instrument at a second time is static, the second time being subsequent to the first time;
determining that the EM location data corresponding to the second time is indicative of the position of the distal end of the instrument at the second time having changed from the reference position by greater than a threshold distance; and
determining a compensated position of the distal end of the instrument based on the EM location data and the determination that the position of the distal end of the instrument at the second time has changed from the reference position by greater than a threshold distance.
