Medical Simulation for Trauma Management
Abstract
We have continued our work on developing the fundamental simulation technologies needed for battlefield trauma treatment training software. New approaches to including haptic feedback for trauma surgery have been created through the integration of robotics and physics-based tissue modeling into a real-time simulation architecture. We have demonstrated interactive models representing both flexible and rigid structures, are continuing to develop techniques for volume deformation and surface warping, and have begun work incorporating fast finite element modeling into our simulation approach. The Visible Human male dataset has been segmented to the extent necessary for the abdominal simulation and polygonal models appropriate for interactive display have been constructed. A novel method for real-time intravacular fluid flow taking advantage of techniques in cellular automata has been implemented. Lastly, we have evaluated software architectures and have developed an expandable distributed real-time control system that allows for the assignment of multiple processors to various computational tasks of the simulation system. We have achieved significant performance increases on our benchmark simulation tests over our previous software architecture.
