Abstract
A method for transforming a bone image data set representing at least a partial image of a long bone to a robotic coordinate system, comprising: generating the bone image data set from a bone image; registering a bone digitizer arm to the robotic coordinate system; generating a digitized bone data set by taking bone surface position measurements with the digitizer arm; and transforming the bone image data set into the robotic coordinate system by performing a best-fit calculation between coordinates of the bone image data set and corresponding coordinates of the digitized bone data set.
