3P1-4 Application of Guided Acoustic Waves for Inversion Calculation of Material Properties in Bones

Abstract

Osteoporosis is a widespread and growing clinical problem with the global aging population increases. Therefore. this paper reports for the first time on inverse estimation of several bone properties from guided-wave measurements in bi-layered bone samples. This study is focused in establish the quality of the bone material properties measured platform, to achieve the goal of quantitative assessment of material properties. The method is based on three steps: the modeling with bi-layer bones phantoms with guided wave on reduction of bone mass, then a laser ultrasound technique is used to measure the experiment data, finally, combined with theoretical dispersion relation and experimental dispersion relation, using global optimization of particle swarm algorithm to inverse estimation of several bone properties.
