Abstract
In recent years, computer-assisted surgery has evolved and developed due to the need to integrate the information derived from different sensory inputs in the operating room and also the necessity to track the surgical operation quantitatively during and after the surgery. The current research in this area envelops all phases of a surgical procedure: preoperative planning, intra-operative registration and guidance, and post-operative follow-ups. A few of the main medical imaging modalities used to plan and perform these operations include ultrasound, X-ray, CT and MRI.

This talk will cover the research currently being conducted at the Image Analysis Laboratory at Queen's University regarding the application of medical imaging modalities in both the preoperative planning and intra-operative registration phases of computer-assisted orthopaedic surgery. With regards to the former, the goal is to reconstruct anatomical models of patients from medical images with little computational cost. Regarding the latter, the aim is to register in real-time, the patient's anatomy to the pre-operative 3D models extracted from the ultrasound, CT and MRI images. These reconstruction and registration techniques have been incorporated in the design of novel user interfaces that will improve intra-operative guidance of surgical tools.
