The Virtual Rat project was developed by the National Biocomputation Center Stanford University and the BioVis Technology Center, Ames Research Center to help train scientists in conducting experiments on various organisms (rats) in a microgravity environment.
The team originally estimated the values of force for the haptic devices but were not satisfied. They wanted to deliver the most realistic haptic feedback in this virtual environment. The project needed accurate material property measurements of various tissues. The project team turned to the Simulation Group at CIMIT where Mark Ottensmeyer, PhD had developed the Tissue Material Property Sampling Tool. The TeMPeST 1D is a tool designed to measure the force-displacement response of solid organ tissues. Together they conducted in vitro tests on a rat kidney and rat liver. The parameters recorded by the TeMPeST 1D can now be incorporated into the tissue models.
