Abstract
We have proposed a novel method to produce biological models using polyurethane elastomer, which has high photoelastic coefficient. And a method to analyze stress states on the model by circular polarized light method. In this paper, we propose stress measurement on biological model by image reconstruction which is a stress measurement method using photoelastic effect. With this method, the cross section of the model was reconstructed accurately by the image reconstruction processing. And, each pixel stress states of not only principal shear stress, but also each stress difference and shear stress can be measured. Consequently, it should be valuable for various applications not only surgical simulations but also hemodynamic studies and pathological studies.
