Acoustic properties of living tissues are an important parameter for quantitative estimation of the tissue structure. It is very important to determine the relationship between the physical and the chemical change of tissue structure and the change of acoustic properties. In this paper, using a new system with high density measuring points, we present the relationship diagram between the speed of sound and attenuation of human heart and liver tissues at 25 MHz. To compare normal and diseased tissues, we investigate the relationship between the sound speed and the attenuation of tissue. A characteristic relationship of the tissue is found in cirrhotic liver and aortic regurgitation tissue.
