Abstract :
The aim of this work was to develop a new computer system to support oncologic surgery in the maxillo-facial area (Maxillo-Facial Surgery System). The system applies DICOM data (Magnetic Resonance Imaging - MRI and Computed Tomography - CT scans) during the phase of virtual planning of surgical scenario, to identify the location and spatial geometry of cancer, as well as it serves to plan resection and reconstruction of bone tissue using bio-implants. The intraoperative phase applies computer aided optical and electromagnetic navigation systems to track the position of surgical instruments and bone segments. This work presents results of planning and computer aided surgery on a skull and mandible phantom and selected results of oncologic patient´s CT scans analysis. The accuracy of the prepared system has been expressed with Target Registration Error value equals about 0.75 mm (when the titanium markers in registration procedure are applied). The system is currently clinically tested in M. Sklodowska-Curie Memorial Cancer Center, Warsaw, Poland.
