This research program is directed to answering the question: "How can we improve the planning and performance of Image-Guided Surgery (IGS)?" IGS provides surgeons with methods for surgical planning and guidance for intra-operative interventions. In general, the procedure is a three step process: i) Medical Image Acquisition, ii) Planning and, iii) Navigation. During image acquisition, the anatomy is scanned using medical imaging (e.g. CT, MRI). In the planning phase relevant data (e.g. bone, cartilage) are extracted from the image dataset and a 3-dimensional (3D) model of the anatomy is constructed and surgical interventions are planned. During the surgery a tracking system, such as an opto-electronic camera, is installed in the operating theater and sensors are rigidly attached to anatomies and surgical instruments. The camera reads the information from these sensors and then computer graphics and registration algorithms are used to render the tracked position of the instruments on the virtual representation of the anatomy and/or the planned instrument trajectory.
