Claim 21:
22. The method according to claim 21 wherein employing the inter-level transforms to obtain intraoperative fiducial points associated with the other spinal levels of the plurality of spinal levels comprises:
(x) employing the registration transform between the pre-selected spinal level and the selected spinal level to transform the intraoperative fiducial points associated with the selected spinal level into the volumetric frame of reference, thereby obtaining transformed intraoperative fiducial points;
(xi) applying the inter-level transform between the pre-selected spinal level and the adjacent spinal level to the transformed intraoperative fiducial points, thereby obtaining estimated adjacent fiducial locations associated with the adjacent spinal level;
(xi) employing the estimated adjacent fiducial locations to determine transformed adjacent fiducial points residing within the segmented surface data associated with the adjacent spinal level;
(xii) employing the registration transform associated with the adjacent spinal level to transform the transformed adjacent fiducial points into the intraoperative frame of reference, thereby obtaining intraoperative fiducial points associated with the adjacent spinal level; and
(xiii) repeating steps (x) and (xii) to determine the intraoperative fiducial points associated with the additional spinal levels of the plurality of spinal levels.
