In order to improve the safety of surgical interventions, computer-aided planning tools obtain increasing clinical acceptance. They enable physicians to inspect 3D models of patient's anatomical structures and provide valuable risk analyses and resection plans.
This information allows for the preoperative assessment of surgical risk and can support the navigation of surgical instruments intraoperatively. However, recent planning systems do not provide adequate user interfaces, since they were designed for the interaction during the pre-operative planning stage. Considering surgical requirements like sterility, work space, and workflow it is impossible for surgeons to interact with a computer using conventional interaction devices like a mouse or a keyboard.
In the talk, a new concept for surgical-computer interaction is presented. The concept is based on clinical scenarios while using the remote control WiiMote (Nintendo) as a primary interaction device during surgical interventions. Furthermore, preliminary results of a clinical user study are discussed.
Christian Hansen studied Computational Visualistics (University of Magdeburg, Germany) with elective courses in medicine. During his years of study he was student research assistant at the Department for Simulation and Graphics at University of Magdeburg, student trainee at the Artificial Intelligence Information Analysis Laboratory at Aristotle University Thessaloniki, Greece, and diploma student at the institute MeVis Research, Bremen, Germany. He graduated as Engineer of Computational Visualistics in 2006 and became a member of MeVis Research. Since 2009 he is scientific assistant at the Institute for Medical Image Computing, Fraunhofer MEVIS, Bremen. His research interest includes intraoperative visualization, medical image processing, and surgeon-computer interaction.
