Outline of Final Research Achievements

In recent years, estimation method of nonlinear elastic parameters has been developed for breast cancer diagnosis because of the knowledge that can determine the breast tissue type by nonlinear elastic parameters. In this study, the estimation method of nonlinear elastic parameters based on vibration characteristics was proposed. Vibration analysis simulator and evaluation experimental system were developed.
