A bone structure is-a highly differentiated coupling tissue and alternatively grows or declines regarding to biological-and/or physiological environments. It is an important, subject in the bioengineering and practical needs to investigate the evaluation method of the mechanical properties of a bone and also to clear the mechanism of the correlation between the structure change of a bone tissue and the aging. In this paper, density and elastic modulus distributions of a bone tissue were analyzed via distributions of surface wave velocity and acoustic impedance of micro parts .of a bone tissue measured using a scanning acoustic microscope (SAM). As a result, the elastic modulus of the canine femur bone showed a little anisotropy.
