Claim 0:
1. A Magnetic Resonance Imaging (MRI)-guided method, comprising:
providing a mount assembly comprising a base adapted to be affixed to a skull of a patient, wherein the mount assembly further comprises first and second arms that are arcuate and spaced apart on opposing sides of a patient access aperture defined by the base, wherein the first and second arms attach to the base, wherein the mount assembly supports a mount that is configured to hold an MRI visible elongate member, wherein the mount is slidably supported by the first and second arms whereby the mount is adjustably, slidably configured to controllably 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 such that, when held in the mount, a lower portion of the MRI visible elongate member is visually accessible via the open space;
automatically determining a scan plane in three-dimensional (3D) MRI space with the MRI visible elongate member held in the mount;
electronically identifying a first intrabody trajectory provided by the mount holding the MRI visible elongate member;
electronically comparing the first intrabody trajectory to a desired intrabody trajectory that intersects a target intrabody site;
electronically calculating positional adjustments of a plurality of positional adjustment members that are coupled to the mount assembly and are spaced apart and independently rotatable, wherein the plurality of positional adjustment members reside in different planes and are configured to move the mount to achieve the desired intrabody trajectory; then
electronically directing a drive system coupled to the plurality of positional adjustment members to automatically rotate the plurality of positional adjustment members based on the calculated positional adjustments which translates the mount to adjust a position of the mount relative to the base which moves the MRI visible elongate member to extend along the desired intrabody trajectory, wherein the drive system is a piezoelectric drive system.
