Claim 19:
20. A Magnetic Resonance Imaging (MRI)-guided method, comprising:
electronically identifying a first intrabody trajectory provided by a mount assembly residing external of and coupled to a skull of patient, wherein the mount assembly comprises a mount with an open center channel that slidably, releasably receives an MRI visible elongate member, wherein the mount assembly further comprises first and second arms that are arcuate and that are coupled to a base configured to attach to the skull of the patient, wherein the first and second arms are spaced apart with a patient access aperture provided by the base extending therebetween, wherein the mount is slidably supported by the first and second arms to allow the mount to slidably travel forward and rearward over a curvilinear path defined by the first and second arms, and wherein an open space extends under each of the first and second arms to the base;
electronically comparing the first intrabody trajectory to a desired intrabody trajectory that intersects a target intrabody site;
electronically calculating positional adjustments of at least first and second positional adjustment members that are spaced apart, separately rotatable and coupled to the mount assembly in different planes to achieve the desired intrabody trajectory; then
automatically directing a drive system coupled to the first and the second positional adjustment members to adjust a position of the mount relative to the base to provide an adjusted second trajectory that extends along the desired intrabody trajectory,
wherein the drive system comprises at least first and second non-ferromagnetic flexible drive cables that are attached to corresponding ones of the first and second positional adjustment members, that extend out of a bore of a magnet associated with an MRI scanner, and that are configured to rotate the respective first and second positional adjustment members to provide an adjusted position of the mount while the patient resides in the bore of the magnet associated with the MRI scanner, and
wherein the method further comprises placing an interventional device in the mount and at the target intrabody site with the mount in the adjusted position.
