抄録

Accurate models of tissue behavior are key elements in supporting system for surgery. Tissue model parameters, however, are inherently uncertain factors that are due to individual specificity. This paper is concerned with the identification analysis of tissue model parameters by use of Mass-Spring-Damper model in conjunction with the Extended Kalman Filter. As a result of evaluation test in numerical simulation, elastic parameter of tissue model converges at the correct value.
