Navigating System for Endoscopic Sinus Surgery Based on Augmented Reality

Medical image processing has led to a major improvement of patient care. The 3D modeling of patients from their CT scan or MRI provides an improved surgical planning and simulation allows training of the surgical gesture before carrying it out. These two preoperative steps can be used intraoperatively with the development of augmented reality. We present a navigating system for endoscope sinus surgery based on augmented reality, which can superimpose the virtual model onto the surgeon's view of the patient, providing accurate spatial information of the patient's sinus structure. The system is comfortable and easy to use in clinical employment.
