Conference paper


Minimally invasive surgery promises to speed patient recovery, as measured by such indices as duration of confinement to bed, hospitalization, postoperative outpatient visits, and rehabilitation. The shortening of the operation itself and elimination of unnecessary procedures reduce surgical bleeding and complications. It also reduces total medical costs and it might be beneficial for the care of aged patients. Minimally invasive surgery is based on preoperative and an intraoperative strategy system for surgical planning and on the volumegraph (augmented reality) navigation system. The purpose of computer-aided surgery (CAS) is to assist in minimally invasive surgery by the integration of medical images and information. This augmented reality and Hivision computer-aided surgery (HivisCAS) system provides a means of realization of minimally invasive surgery.
