 note = {This study presents a method to evaluate anisotropic mechanical properties of a bone tissue using a scanning acoustic microscope (SAM). The measurement theory was constructed based on transverse isotropy of the bone tissue. Density and elastic modulus of it were analyzed via distributions of leaky surface wave velocity and acoustic impedance of micro parts of bone tissue measured using SAM. Velocity of the leaky surface wave was measured in the directions from longitudinal axis to transverse axis of long bone by rotating a lens slit attached to the front of a point focus acoustic lens. Anisotropic elastic modulus were determined by using orthotropic elastic constitutive equations and wave equations. Femur bones of elderly human and young beagle dog were measured by this method. It was found that the elastic modulus of femur bone of young canine showed more anisotropy than that of elderly human.},
