One or more implementations are described herein for improved instrument tracking. In a surgical navigation system, one implementation stores a plan for an image guided procedure, before conducting the procedure. This plan includes a path to be traversed by a medical instrument during the procedure. An image of the patient's anatomy displayed with a superimposed a pictorial representation of the path on the image. A transpoder coupled to the medical instrument and emits a signal while inside the patient's body. A position and/or orientation of the transponder (and the instrument) is determined based, at least in part, upon the received transponder signal. |
