Abstract
A method for tracking an interventional medical device in a patient includes interleaving, by an imaging probe external to the patient, a pulse sequence of imaging beams and tracking beams to obtain an interleaved pulse sequence. The method also includes transmitting, from the imaging probe to the interventional medical device in the patient, the interleaved pulse sequence. The method further includes determining, based on a response to the tracking beams received from a sensor on the interventional medical device, a location of the sensor in the patient.
