| Outline of Final Research Achievements |
Ultrasound elastography is now widely used in many clinical fields for visualization of tissue hardness. Although its basic principles are categorized into two methods, there remain problems to be solved: strain image by static method is qualitative, while shear wave imaging by dynamic method is subjective to artifact due to inhomogeneous speed of shear wave. Moreover, imaging of tissue viscosity has not been put in practice. In this research, we aim to develop the viscoelastography, that is, technology of quantitative imaging of viscosity and elasticity of tissue for improvement in diagnosis of diseases such as cancer and chronic hepatitis by integration of static and dynamic excitation of tissue
