<p>A method for re-registration between a robotic coordinate system and an image data set, said method, comprising: providing an image data set that has been registered within a robotic coordinate system based upon an initial bone (20) position within the robotic coordinate system; locating at least three conserved points (P1, P2, P3) fixed relative to the initial bone (20) position prior to any detectable change in bone (20) position from the initial bone (20) position; relocating the same three conserved point (P1, P2, P3) after bone (20) motion may have occurred to determine the locational change in the three conserved points (P1, P2, P3); and re-register the image data set within the robotic coordinate system based on the locational changes.</p> |
