Needle Steering and Model-Based Trajectory Planningined using numerical needle insertion models that include needle deflection and soft tissue deformation. This concept is used in conjunction with a potential-field-based path planning technique to demonstrate needle tip placement and obstacle avoidance. Results from open loop insertion experiments a

Brain Shift Correction Based on a Boundary Element Biomechanical Model with Different Material Propehese deformations a biomechanical model of the brain is proposed. Not only elastic tissues, but also fluids are modeled, since an important volume of the head contains cerebrospinal fluid, which does not behave like soft tissues. Unlike other approaches, we propose to solve the differential equation

Mesh Topology Identification for Mass-Spring Modelsntages of FEM are accuracy and realism. Furthermore, the model allows the direct integration of experimentally obtained biomechanical tissue parameters. However, computation times remain high, limiting real-time application of the method. In contrast to this, the main advantage of MSS is low computa

Real-Time Synthesis of Bleeding for Virtual Hysteroscopy simulator not only tests a surgeon to deal with critical issues, but also affects the environment by obscuring the view in which the surgeon has to operate. For any virtual reality surgical simulator, bleeding has to be treated, while at the same time the bleeding has to be responsive to any feedba
