1. An endovascular probe, comprising:
a loopless antenna comprising a conductor;
a tracking coil with a first end and a second end; and
a switchable coupling coupled to the conductor and the first end of the tracking coil, the switchable coupling disposed at a distal tip of the endovascular probe, wherein:
when the switchable coupling is in a first state, the conductor of the loopless antenna is in electrical communication with the first end of the tracking coil and the endovascular probe is in a tracking probe mode; and
when the switchable coupling is in a second state, the conductor of the loopless antenna is not in electrical communication with the first end of the tracking coil and the endovascular probe is in an imaging probe mode,
wherein each of the tracking coil, the switchable coupling and the loopless antenna use a shared transmission cable including the conductor.
