13. A computerized method for evaluating registration accuracy for different digitization regions on a bone model, the method comprising:
determining a first plurality of simulated registration points relative to a first set of digitization regions on the bone model;
performing a first registration registering locations of the first plurality of simulated registration points to locations of a first plurality of predetermined registration points on a surface of the bone model;
determining a first accuracy of the first registration;
determining a second plurality of simulated registration points relative to a set of second digitization region on the bone model, wherein at least one digitization region in the second set of digitization regions is different than at least one digitization region in the first set of digitization regions;
performing a second registration registering locations of the second plurality of simulated registration points to locations of a second plurality of predetermined registration points on a surface of the bone model;
determining a second accuracy of the second registration; and
comparing the first accuracy and the second accuracy.
