Patent ID: 8494613

Claim:
A system to determine and illustrate a location of an instrument using a registration between two tracking systems, comprising: a first tracking device operable with a first tracking system to determine a location of the first tracking device in a first navigational domain, said first tracking system is an electromagnetic tracking system and the first navigational domain is defined by an electromagnetic field generated by an electromagnetic localizer of the first tracking system; a second tracking device operable with a second tracking system to determine a location of the second tracking device in a second navigational domain, said second tracking system is an electro-potential tracking system and the second navigational domain is defined by a current injected into a volume between at least a first injection electrode and a second injection electrode; an instrument including a first portion and a second portion, the first tracking device is associated with the first portion of the instrument and the second tracking device is associated with the second portion of the instrument; wherein the second portion of the instrument surrounds at least a selected portion of the first portion of the instrument and is moveable relative to the first portion of the instrument; and a calibration jig having an exterior indication module associated with a fixed base; wherein the exterior indication module is operable to illuminate a target associated with the first tracking system to indicate a location of the first tracking device relative to the calibration jig.
