Claim 16:
17. A method for simultaneously tracking multiple sensors in a medical intervention, the method comprising:
receiving, from a first passive ultrasound sensor, a first signal with first sensor information indicative of a location of the first passive ultrasound sensor;
receiving, from a second passive ultrasound sensor, a second signal with second sensor information indicative of a location of the second passive ultrasound sensor;
combining the first signal and the second signal into a combined signal for transmission over one and only one channel;
performing a signal modification with respect to at least one of the first signal and the second signal that enables identification of the first signal and the second signal in the combined signal;
transmitting the combined signal over the one and only one channel to a tracking system configured to track the first interventional medical device and the second interventional medical device; and
determining, by the tracking system, the location of the first passive ultrasound sensor and the location of the second passive ultrasound sensor from the combined signal based on the signal modification.
