Patent ID: 8768023

Claim:
A method for determining an axial direction of a bore of a bone fixator, executable in a computer system, the method comprising the steps of: obtaining images of the bore, wherein images of the bore are taken from a first position to obtain a first overlapping image of a first bore surface and a second bore surface of the bore, and from a second position to obtain a second overlapping image of the first bore surface and the second bore surface; calculating perpendicular bisectors, wherein the first overlapping image and the second overlapping image are separately processed by a processing unit so as to obtain through calculation a first perpendicular bisector in the first overlapping image and a second perpendicular bisector in the second overlapping image; determining spatial planes, wherein the first position and the first perpendicular bisector define a first plane, and the second position and the second perpendicular bisector define a second plane; and obtaining the axial direction of the bore, wherein the processing unit calculates an intersection of the first plane and the second plane, and the intersection defines the axial direction of the bore.
