Abstract

For the pre-operative definition of a surgical workspace for Navigated Control^® Functional Endoscopic Sinus Surgery (FESS), we developed a semi-automatic image processing system. Based on observations of surgeons using a manual system, we implemented a workflow-based engineering process that led us to the development of a system reducing time and workload spent during the workspace definition. The system uses a feature based on local curvature to align vertices of a polygonal outline along the bone structures defining the cavities of the inner nose. An anisotropic morphologic operator was developed solve problems arising from artifacts from noise and partial volume effects. We used time measurements and NASA's TLX questionnaire to evaluate our system.
