Studies and modelling the effect of porosity on the microstructure and properties of cancellous bone by the ultrasound method

Abstract

The work presented in this paper presents a new methodology for detecting the changes in the trabecular structure due to osteoporosis. This paper focuses on the experimental characterisation of the microstructure and properties of cancellous bone by the ultrasound method. The aim of this work was to study the feasibility of controlling the bone porosity by the ultrasonic transmission method. This power is based mainly on the measurement of ultrasonic parameters to verify the ability of the ultrasound technique to detect the bone porosity degree. The ultrasonic propagation in cancellous bone is modelled using the Schoch theory and the Biot theory. This study concerns the cancellous bone which is most affected by the osteoporosis. After resolution of the direct problem, the second part of this paper concern the characterisation of porous bone by solving the inverse problem means to calculate the porosity from acoustic data.
