Medicine Meets Virtual Reality- MMVR 2001

Half-day tutorial on medical simulation and training

Simulating minimally invasive surgical procedures in virtual environments: 

MODELING
Summary:
This tutorial will focus on modeling aspect of medical simulation. The topics covered in this tutorial will include modeling for 3D visualization, physics-based models for graphical and haptic display of soft tissue behavior, models for simulating instrument-tissue interactions, and models for measuring tissue properties and evaluating surgical skills of the user. Although some overview of the work in the field will be given, our intend is to highlight the major research problems in the area of modeling and provide the audience with technical and practical implementation details.
