Abstract
The present disclosure relates to systems and methods to perform a surgical procedure. The systems and methods utilize MRI-compatible fiducial markers including a body having at least one feature configured to receive an MRI-compatible and MRI-visible material and to allow registration of a navigational tool. The MRI-compatible fiducial markers can be affixed to a bone of a patient. The registered navigational tool can be used to advance a surgical tool along a navigational path to perform a surgical procedure.
Claims20
An MRI compatible fiducial assembly comprising:
- a) a predetermined shaped body having a planar upper surface, a thickness and a planar lower surface generally parallel said planar upper surface;
- b) a plurality of formed cavities extending into said shaped body;
- c) at least one bore extending through said shaped body, said bore adapted to receive an MRI compatible bone anchor;
- and
- d) an MRI-compatible and MRI-visible material for insertion in each of said formed cavities and being adapted for navigational tool registration.
An MRI compatible fiducial assembly comprising:
- a) a shaped body having an upper surface, a thickness and a lower surface generally parallel said upper surface, said shaped body having at least one lower body extending from said lower surface;
- b) a raised body structure extending upward from said upper surface of said shaped body;
- c) a plurality of formed cavities extending into said raised body structure of said shaped body;
- d) a bore extending through said shaped body, said bore adapted to receive an MRI compatible bone anchor;
- and
- e) an MRI-compatible and MRI-visible material for insertion in said formed cavities.
An MRI compatible fiducial assembly comprising:
- a) a shaped body having an upper surface, a thickness and a lower surface, a raised body structure extending upward from said upper surface of said shaped body, said shaped body and said raised body having rounded peripheries;
- b) a plurality of formed cavities extending into said raised body of said shaped body, said plurality of formed cavities including cavities of two different predetermined sizes adapted for the registration of different navigational tools;
- c) a bore extending through said shaped body, said bore adapted to receive an MRI compatible bone anchor;
- and
- d) an MRI-compatible and MRI-visible material for insertion in said formed cavities.
