Claim 14:
15. A system for facilitating imaging of a patient's heart 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 a coronary vessel, 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 into a second coronary vessel and carrying a second positional sensor; and
a processor coupled to the first and second positional sensors for receiving signals from the first and second positional sensors to generate an internal reference frame substantially fixed relative to the first and second coronary vessels to identify an orientation of the patient's heart within the external reference frame, the processor further 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.
