SYSTEM AND METHOD FOR PERFORMING IMAGE DIRECTED ROBOTIC ORTHOPEDIC PROCEDURES WITHOUT A FIDUCIAL REFERENCE SYSTEM

摘要

A method for transforming a bone image data set (16) representing at least a partial image of a long bone to a robotic coordinate system, comprising: generating the bone image data set (16) from a bone image; registering a bone digitizer arm (100) to the robotic coordinate system; generating a digitized bone data set (17) by taking bone surface position measurements with the digitizer arm (100); and transforming the bone image data set (16) into the robotic coordinate system by performing a best-fit calculation between coordinates of the bone image data set (16), and corresponding coordinates of the digitized bone data set (17).
