Abstract
A surgical navigation system is disclosed herein. The surgical navigation system includes a tracking system, a field generator operatively connected to the tracking system, a field sensor operatively connected to the tracking system, and an electrostatic shield circumscribing the field sensor. The electrostatic shield is adapted minimize capacitive coupling between the field generator and the field sensor.
