Image Guided Surgery (IGS) – Definition?
• General term used for any surgical procedure wheresurgeons employs tracked surgical instruments inconjunction with preoperative or intraoperative images inorder to indirectly guide the procedure
• IGS was originally developed for treatment of brain tumors
• Various applications of navigations for neurosurgery havebeen widely used for almost two decades
