| Research Abstract |
Accurate values of the elastic modulus of human tissues are key elements in a computer-aided surgical system using a deformable organ model. In this research project we developed a quantitative identification method for the elastic modulus, where combinations of robotic force measurement, three-dimensional medical imaging, finite element analysis, and nonlinear optimization are used. Experiments using tissue phantoms and experimental systems were carried out to verify the effectiveness of the proposed method. The experimental results demonstrate that the method is able to concurrently identify the Young's moduli of the tissues.
