Although careful planning is a key for successful surgery, conventional computer assisted application cannot support detailed planning because it cannot simulate complex physical behavior of soft tissues provided by a series of surgical procedures. This paper proposes an adaptive physics-based framework that simulates both interactive cutting and accurate deformation on reconstructed virtual bodies. The framework modifies tetrahedral mesh via cutting manipulation and dynamically constructs stiffness matrix required for finite element based simulation. Using the proposed methods, the authors developed a strategic planning system that supports decision of surgical approach and applied measured clinical dataset of an aortic aneurysm case. Some experiments and usability tests confirmed the developed system enables preoperative rehearsal of constructing surgical fields and efficiently supports strategic planning.
