Computer Aided Liver Surgery Planning based on Augmented Reality Techniques

A system for liver surgery planning is reported that enables physicians to visualize and refine segmented input liver data sets, as well as to simulate and evaluate different resection plans. The system supports surgeons in finding the optimal treatment strategy for each patient and facilitates the data preparation process. Using augmented reality eases complex interaction with 3D objects and contributes to a user-friendly design. First practical evaluation steps have shown a good acceptance. Evaluation of the system is ongoing and future feedback from surgeons will be collected and used for design refinements.
