Investigation of an anisotropic tortuosity in a biot model of ultrasonic propagation in cancellous bone.

The modeling of ultrasonic propagation in cancellous bone is relevant to the study of clinical bone assessment. Historical experiments revealed the importance of both the viscous effects of bone marrow and the anisotropy of the porous microstructure. Of those propagation models previously applied to cancellous bone, Biot's theory incorporates viscosity, but… CONTINUE READING
