Abstract
We have developed a method of quantitative analysis of trabecular orientation on the cancellous bone by a Fourier analysis of the soft X-ray image. The relationship between the trabecular orientation and tensile modulus E was investigated on the cancellous bone specimens removed from the fresh bovine tibia. The proportion of trabeculae in a group at an angle θ to the loading direction, f(θ), and the volume fraction of the trabeculae, Vf, were obtained by applying the soft X-ray image of the test specimen. The equivalent volume fraction in the loading axis, Vfeq, was determined from a netting analysis, that is, Vfeq = Σ cos4θ f(θ)Vf. A linear regression was performed, giving the equation, E = -119+15234 Vfeq (MPa) ( r=0.96, P<0.01 ).
