Computer-aided surgical simulation is a topic of increasingly extensive research. Computer graphics, geometric modeling and finite-element analysis all play major roles in these simulations. Furthermore, real-time response, interactivity and accuracy are crucial components in any such simulation system. A major effort has been invested in recent years to find ways to improve the performance, accuracy and realism of existing systems.In this paper, we extend the work of [Sela et al. 2004], in which we used Discontinuous Free Form Deformations (DFFD) to artificially simulate real-time surgical operations. The presented scheme now uses accurate data from a Finite-Element Model (FEM), which simulates the motion response of the tissue around the scalpel, during incision. The data is then encoded once into the DFFD, representing the simulation over time. In real-time, The DFFD is applied to the vertices of the surface mesh at the actual incision location and time. The presented scheme encapsulates and takes advantage of both the speed of the DFFD application, and the accuracy of a FEM. In addition, the presented system uses a haptic force feedback device in order to improve realism and ease of use.
