Claim 0:
1. A system for tracking at least one bone in computer-assisted surgery, comprising:
a processing unit; and
a non-transitory computer-readable memory communicatively coupled to the processing unit and comprising computer-readable program instructions executable by the processing unit for:
obtaining backscatter images of the at least one bone from a tracking device in a coordinate system, as positioned on a tool interfacing with an anatomical part surrounding the bone or with the bone;
generating a three-dimensional geometry of a surface of the at least one bone from the backscatter images, the three-dimensional geometry of the surface being in the coordinate system;
determining a position and orientation of the at least one bone in the coordinate system by matching the three-dimensional geometry of the surface of the at least one bone to a three-dimensional model of the bone; and
continuously outputting the position and orientation of the at least one bone in the coordinate system to an interface for providing guidance in altering the bone.
