Claim 0:
1. A method of determining an intraoperative orientation of a spine, the method comprising:
processing volumetric image data pertaining to a spine to generate multi-level surface data characterizing a bone surface of the spine;
processing the multi-level surface data to generate segmented surface data on a per-level basis for each level of a plurality of spinal levels;
for each spinal level of the plurality of spinal levels, performing a surface-to-surface registration between the segmented surface data associated with said each spinal level and intraoperative surface data characterizing surface regions associated with each spinal level of the plurality of spinal levels, thereby obtaining a registration transform associated with said each spinal level; and
employing the registration transforms associated with the plurality of spinal levels to generate and display one or more parameters numerically quantifying a relative intraoperative orientation and/or relative intraoperative position of at least one of the spinal levels.
