| Abstract: | The aim of this thesis was to develop and evaluate a new method to improve image-guided surgery (IGS) for treatment of complex pelvic fractures using object-oriented 3D navigation (OON). Conditions influencing the performance of an optical tracker, such as design of the reference frame, warming up of the tracker, filter settings and position of the reference frame with respect to the tracker were first evaluated and optimized. The OON system was then combined with the Microsoft HoloLens to track objects in an augmented reality (AR) setting. The accuracy of the OON system with and without AR was evaluated by placing 3D objects accurately at preplanned positions in an optimal situation and calculating the measured deviations. Accuracy of the system with and without AR was 0.60 mm (sd = 0.16) and 0.71 mm (sd = 0.24), respectively. Using the system as guidance for placing objects at planned positions showed mean deviations of 0.70 mm (sd = 0.44) without and 1.81 mm (sd = 0.68) with AR. The guidance using AR should be improved before the step to clinical implementation is possible. |
