Abstract:
1. A computer aided surgical navigation system to navigate a procedure relative to a physical space of a patient with registration of image space defined by image data to the physical space, comprising: a tracking system having a localizer and a tracking device; a plurality of fiducial markers operable to be associated with the patient and each of the plurality of fiducial markers defining a respective fiducial marker identification; an instrument associated with the tracking device, wherein the instrument includes a fiducial marker contact portion defining a single fiducial marker association point configured to contact each of the fiducial markers such that the tracking system is operable to track a location of the respective fiducial marker identification when the instrument is contacting each of the fiducial markers; a processor operable with the tracking system to determine a position of the single fiducial marker association point in the physical space; a memory system operable to store: a display device operable to display the image data; wherein the processor is operable to execute a first set of instructions to compare the image data of the patient and the plurality of fiducial markers to the predetermined fiducial template to determine the fiducial points relating to the respective fiducial marker identification of at least selected ones of the fiducial markers in the image data including: wherein the processor is further operable to execute a second set of instructions to match the determined plurality of fiducial points in image data that defines the image space to the respective fiducial marker identification in physical space including: wherein the processor in executing the first set of instructions further includes:
