In the last decades, Quantitative Ultrasound (QUS) has become a widespread method of examining human bones to assess their current state and detect developing osteoporosis. This is mostly based on empirical experimental data, while theoretical (computer) simulation of wave processes in bones and bone-like structures (so-called phantoms) provides an insight into the guided wave regularities in such structures. A parametric study reveals the influence of various factors that could be used in osteoporosis diagnostics as signs of latent bone degradation. The present work gives examples of such a case study using the Green’s matrix-based semi-analytical model for guided wave excitation and propagation in elastic multilayered waveguides mimicking typical property variations in real bones covered by a soft tissue.
