1. A system for imaging and magnetically navigating a medical device within an operating region in a subject'"'"'s body, the system comprising:

  • a first C-arm;

    a first imaging beam source and a first imaging beam receiver mounted on the first C-arm and positioned to be disposed on opposite sides of the operating region to image the operating region;

    a second C-arm;

    a second imaging beam source and a second imaging beam receiver mounted on the second C-arm and positionable to be disposed on opposite sides of the operating region to image the operating region;

    the second C-arm being movable between an imaging position in which the second imaging beam source and second imaging beam receiver on the second C-arm are positioned so that the first and second imaging beam sources and first and second imaging beam receivers are in the same plane, and a stowed position in which the second C-arm is in a navigating position; and

    a pair of magnetic pods movably mounted on the first C-arm, the magnetic pods being movable between a navigating position in which the pods are disposed on opposite sides of the operating region in the same plane as the second imaging beam source and the second imaging beam receiver, for applying a navigating magnetic field of at least 0.08 T in any direction to the operating region, and a stowed position in which the magnets are moved out of the plane to accommodate the second imaging beam source and second imaging beam receiver on the second C-arm in its imaging position.
