Claim 0:
1. A system for facilitating imaging a patient during a medical procedure, comprising:
an electromagnetic field generator for generating an electromagnetic field around a desired region of a patient's body to provide an external reference frame;
a first elongate member comprising a proximal end, a distal end sized for introduction into the patient's body, and a first distal portion carrying a first positional sensor;
a second elongate body comprising a second distal portion advanceable from the first distal portion and carrying a second positional sensor such that a distance between the first positional sensor and the second positional sensor is adjustable; and
a processor coupled to the first and second positional sensors for receiving signals from the first and second sensors generated in response to the electromagnetic field, the processor configured to identify when the first and second positional sensors move relative to the external reference frame to identify corresponding movement of the patient's body.
