Claim 0:
1. A method of determining a location of a treatment device during an ablation procedure within a patient, the method comprising:
delivering ablation energy from an ablation electrode of the treatment device to an area of tissue;
delivering navigation energy to a plurality of external patch electrodes from a plurality of navigation energy sources, the navigation energy delivered by each of the plurality of navigation energy sources being a same frequency;
transmitting a plurality of voltage signals from a mapping electrode of the medical device to a processing unit, the processing unit time-division multiplexing the voltage signals, wherein the processing unit time-division multiplexes the voltage signals in each of a first plane, a second plane, and a third plane; and
determining a location of the medical device within a patient based on the time-division multiplexed voltage signals.
