23. A surgical system comprising:
-
a patch adapted to reside on a patient, the patch having an MRI visible grid; an MRI compatible articulating arm with first and second opposing end portions, the first end portion being supported directly or indirectly by an MRI scanner bed, the second end portion configured to reside over a patient; a trajectory frame held by the articulating arm; and a processor for defining an entry site to an intrabody target in the patient using the grid. - View Dependent Claims (24, 25)

26. A method for accessing a target intrabody surgical site for an MRI guided surgical procedure, comprising:
-
providing an articulating arm so that it is supported directly or indirectly by a scanner bed; adjusting the articulating arm to position a mounting plate attached to the articulating arm over a desired entry site into a target intrabody location; and performing an MRI guided procedure while the mounting plate is held by the articulating arm over the intrabody location. - View Dependent Claims (27, 28, 29)

30. A medical tool for an MRI guided procedure, comprising:
a plurality of discrete segments with hinge joints, at least some of the discrete segments being configured to be releasably attachable in situ to form at least a portion of a non-ferromagnetic articulating arm, wherein one of the segments includes a mounting member for holding a trajectory guide frame thereon thereby allowing a user to assemble a desired configuration of the articulating arm to accommodate a particular patient or surgical procedure.
- 31. A base member for an MRI guided medical procedure, the base member being non-ferromagnetic and having at least one predefined anchor location thereon for releasably attaching an articulating arm thereto, wherein the base member is configured to reside on a scanner bed and translate with the patient in and out of a magnet bore, and wherein the base member comprises patient fixation means.
