Velocity dispersion in trabecular bone: Influence of multiple scattering and of absorption

Abstract: Speed of sound measurements are widely used clinically to assess bone strength. Trabecular bone is an attenuating composite material in which negative values of velocity dispersion have been measured, this behavior remaining poorly explained physically. The aim of this work is to describe the ultrasonic propagation in trabecular bone modeled by infinite cylinders immersed in a saturating matrix, and to derive the physical determinants of velocity dispersion. A homogenization model accounting for the coupling o… Show more

“…19,27 Negative dispersion has been measured not only in trabecular bone [29][30][31][32][33] and cortical bone 34 in vitro but also in trabecular bone-mimicking phantoms. 35,36 Several models have been proposed that predict negative dispersion including multilayer models, 31,37 multiple scattering models, 38 and independent scattering models. 39 The objective of this study was to investigate the potential value of separating the fast waves and slow waves for determining the attenuation properties of cancellous bone and to compare the results of time-domain and frequency-domain methods for the analysis of attenuation.…”

“…The results found in the literature on the effect of absorption on propagation in trabecular bone are contradictory. Haiat et al, 22 using a model of MS, found that accounting for absorption in the trabeculae had very little effect on Fig. 3.…”

“…22 When MS occurs during propagation in heterogeneous structures such as bone, ultrasound backscattered signals contain both single scattering (SS) and MS contributions. In SS, the incident ultrasonic wave is subjected to only one scattering event before traveling back to the transducer.…”

“…Several theories of wave propagation in viscoelastic media have been applied to the trabecular bone considered as a two-phase composite, among them are the multiple-scattering phenomena [1][2][3][4], an alternative theoretical approach in which the bone is considered as multilayer composite introduced in [5][6] and Biot's model [7][8][9][10][11].…”
