Abstract: A controller (120) for simultaneously tracking multiple sensors in a medical intervention includes a circuit (121-181) that causes the controller (120) to execute a process. The process executed by the circuit (121-181) includes receiving first and second signals respectively from a first and a second passive ultrasound sensor (S2) used in the medical intervention. The first and second signals respectively include first and second sensor information indicative of respective locations of the first and the second passive ultrasound sensor (S2). The process executed by the circuit (121-181) also includes combining (120) the first signal and the second signal for transmission over only one channel, and providing the first signal and the second signal over the only one channel to a system (190) that determines the location of the first passive ultrasound sensor (S1) and the location of the second passive ultrasound sensor (S2) and that has only the one channel to receive the first signal and the second signal.

Abstract: A system for determining location of an interventional medical device within a patient includes a controller that controls an ultrasound probe to emit imaging beams at different times and angles relative to the ultrasound probe. The system also includes an interventional medical device with an attached sensor that receives the imaging beams together with repetitive noise. The controller further identifies the repetitive noise received at the sensor, including identifying the rate at which the repetitive noise is repeated and identifying the times at which the repetitive noise is received at the sensor. The controller further offsets the repetitive noise in signals received at the sensor by interpolating the signals based on the imaging beams. The controller determines the location of the interventional medical device based on the offset signals.
