Virtual splint registration for electromagnetic and optical navigation in orbital and craniofacial surgery

Abstract In intra-operative navigation, a registration procedure is performed to register the patient’s position to the pre-operative imaging data. The registration process is the main factor that determines accuracy of the navigation feedback. In this study, a novel registration protocol for cranio...
