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.
