Abstract :
Interactive image-guided (IIG) surgery involves the synchronal display of the tip of a surgical device on preoperative scans. This display allows the surgeon to locate the present surgical position relative to the final site of surgical interest. A technique for IIG surgery based on a 6-degrees-of-freedom articulated arm is presented. Design accuracy for the arm is less than 0.1 mm, and the present implementation has a submillimetric accuracy. The display can show the surgical position on any tomographic image set with simultaneous display on up to three image sets. Laboratory results and clinical applications are discussed.
