1. A system for tracking a sensor, the system comprising:
a sensor configured to receive ultrasound tracking beams and transmit a response to the ultrasound tracking beams; and
a processor communicatively coupled to an imaging probe, the processor configured to:
interleave a pulse sequence of ultrasound imaging beams and the ultrasound tracking beams to obtain an interleaved pulse sequence,
synchronize transmission of the interleaved pulse sequence and receipt of the ultrasound tracking beams by the sensor based on establishing a timing pattern for the transmission of the interleaved pulse sequence and the receipt of the ultrasound tracking beams,
transmit the interleaved pulse sequence to the sensor, and
based on the response to the ultrasound tracking beams from the sensor, determine a location of the sensor.
