Classification: CPC A  G | IPC A  G

Claim 14:
15. A system, comprising:
an instrument comprising a set of one or more electromagnetic (EM) sensors, the EM sensors configured to generate EM location data indicative of a position of a distal end of the instrument;
one or more processors; and
at least one computer-readable memory in communication with the one or more processors and having stored thereon computer-executable instructions to cause the one or more processors to:
determine a reference position of the distal end of the instrument at a first time based on the EM location data;
determine that the distal end of the instrument at a second time is static, the second time being subsequent to the first time;
determine that an EM distortion has occurred based on the reference position at the first time and the EM location data corresponding to the second time based at least in part on a threshold distance; and
determine a compensated position of the distal end of the instrument based on the EM location data and the determination that an EM distortion has occurred based on the reference position and the EM location data corresponding to the second time based at least in part on a threshold distance.
