Abstract

It is generally difficult to determine the material values of human tissue to input into an organ deformation model, because the material properties of human tissues are inherently uncertain because of their individual differences. In our work, we developed a promising approach that allows identification of the material parameters of the organ model by using information obtained during surgery. The effectiveness of the method was shown through both numerical and physical experiments. As a result of both experiments, it was shown that the material parameters of the organ model were accurately identified.
