Method for establishing a three-dimensional representation of a bone from image data
First Claim
1. A method for preparing a virtual three-dimensional representation of a first portion of a bone comprising the steps of:
- obtaining, from a first orientation with respect to the first portion of the bone, first image data of the first portion of the bone;
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;
generating a three-dimensional (3D) virtual representation of the first portion of the bone; and
displaying the 3D virtual representation of the first portion of the bone, the displayed 3D virtual representation having an orientation, the orientation of the displayed 3D virtual representation being determined using at least the difference between the first and second orientations from which the first and second image data were obtained.

Abstract
The present invention relates to a 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.

27. A method for preparing a virtual three-dimensional representation of a first portion of a bone comprising the steps of:
-
obtaining, from a first orientation with respect to the first portion of the bone, first two-dimensional image data of the first portion of the bone;
obtaining, from a second, different orientation with respect to the first portion of the bone, second two-dimensional image data of the first portion of the bone;
generating, based on at least the first and second image data, a virtual representation of the first portion of the bone, the virtual representation having a lower symmetry than the first portion of the bone; and
overlaying, on a display device, (i) an image of the virtual representation of the first portion of the bone and (ii) an image of the first portion of the bone, wherein an orientation of the displayed virtual representation is indicative of an intraoperative orientation of the first portion of the bone. - View Dependent Claims (28, 29, 30)

31. A system configured to prepare a virtual three-dimensional representation of a first portion of a bone, the system comprising:
-
a display device; and
a processor in communication with the display device, the processor configured to;
receive first two-dimensional image data of the first portion of the bone, the first two-dimensional image data having been obtained from a first orientation with respect to the first portion of the bone;
receive second two-dimensional image data of the first portion of the bone, the second two-dimensional image data having been obtained from a second, different orientation with respect to the first portion of the bone;
generate, based on at least the first and second image data, a virtual representation of the first portion of the bone, the virtual representation having a lower symmetry than the first portion of the bone; and
overlay, on the display device, (i) an image of the virtual representation of the first portion of the bone and (ii) an image of the first portion of the bone, wherein an orientation of the displayed virtual representation is indicative of an intraoperative orientation of the first portion of the bone.
