ARSyS-Tricorder - Entwicklung eines Augmented Reality Systems für die intraoperative Navigation in der MKG Chirurgie

We present in this paper the development of a novel Augmented Reality System for intra-operative navigation in reconstructive, maxillofacial surgery. The system is going to be integrated into the OR at University clinics of the Technical University of Munich. Therefore it is driven by low-cost PC machines and capable of facing medical CE certification. The system provides navigational aid during reconstructive maxillofacial surgery. It displays, e.g. the autologous transplant, nerves, vessels, and tumor onto the patient who is tracked by an infrared tracking system. The also tracked surgeon perceives these data structures by passive stereo glasses as three-dimensional, stereoscopic objects while looking through the tracked AR display system that consists of a approximately DIN A4 display screen and a semitransparent mirror. The display system is attached to an OR lamp arm and thus can be positioned above the patient's pelvis (donor site for the transplant) and above the patient's face respectively.
