1. An electromagnetic navigation system for guiding and tracking an interventional tool within an anatomical region, the electromagnetic navigation system comprising:
a guidewire configured to be inserted into the anatomical region, the guidewire comprising a plurality of guidance electromagnetic sensors configured to generate guidance data that includes (i) at least one of a position and an orientation of the guidewire relative to the anatomical region and (ii) a position of each of the guidance electromagnetic sensors relative to a reference position;
a hub detachably coupled to the interventional tool, the hub configured to be at least one of translated and rotated relative to the guidewire, the hub comprising a tracking electromagnetic sensor configured to generate tracking data that includes (i) at least one of a position and an orientation of the hub relative to the guidewire and (ii) a position of the tracking electromagnetic sensor relative to the reference position; and
a navigation controller configured to determine at least one of a position and an orientation of the interventional tool relative to the guidewire based on distance of the position of the tracking electromagnetic sensor of the hub from the position of each of the guidance electromagnetic sensors of the guidewire.
