Possible approaches
CT-based Not feasible: cannot register!
Fluoroscopy-based [Nolte et al, Phillips]
virtual fluoroscopy: moving objects on images
+ fewer fluoroscopy images, no preop CT
– 2D images, less complete, no preop planning
CT + Fluoro-based [Lavallee, Joskowicz]
3D bone fragments from preop CT, show
3D view, fluoroscopic images for registration only
+ 3D model, wider field of view, preop planning
– requires extra preop CT study
