A system for imaging and magnetically navigating a medical device within an operating region in a subject's body is provided that comprises a first C-arm and a second C-arm. The system comprises an imaging beam source and an imaging beam receiver mounted on the first C-arm that are positioned to be disposed on opposite sides of the operating region to image the operating region. Some embodiments comprise a pair of magnetic pods, which are movably mounted on either the first or second C-arm. Some embodiments comprise magnetic pods that are movable between an imaging position and a navigating position in which the pods are disposed on opposite sides of the operating region in the same plane as at least one imaging beam source. The magnetic navigation units may apply a navigating magnetic field of at least 0.08 T in any direction to the operating region. In some embodiments of the invention, the second C-arm is movable between an imaging position in which the imaging beam source and imaging beam receiver on the second C-arm is positioned so that the imaging beam sources and receivers are in the same plane.
