A system and method for preparing a virtual three-dimensional
representation of a first portion of a bone. The method may comprise
obtaining, from a first orientation with respect to the first portion of
the bone, first image data of the first portion of the bone and
obtaining, from a second, different orientation with respect to the first
portion of the bone, second image data of the first portion of the bone.
A three-dimensional (3D) virtual representation of the first portion of
the bone may be generated. The 3D virtual representation of the first
portion of the bone may be displayed. The displayed 3D virtual
representation may have an orientation, determined using at least the
difference between the first and second orientations from which the first
and second image data were obtained.
