Trabecular bone plays a significant role in maintaining bone structural integrity. Its density is
a significant determinant of bone strength and fracture risk, but there is still unexplained …

Ultrasound is now a clinically accepted modality in the management of osteoporosis. The
most common commercial clinical devices assess fracture risk from measurements of …

Ultrasonic wave propagation in human cancellous bone is considered. Reflection and
transmission coefficients are derived for a slab of cancellous bone having an elastic frame …

The present study was designed to evaluate the relationships between ultrasonic
backscatter, density, and microarchitecture of cancellous bone. The slopes of the frequency …

Although it has been more than 20 years since the first recorded use of a quantitative
ultrasound (QUS) technology to predict bone fragility, the field has not yet reached its …

Objectives As are the attenuation coefficient and sound speed, the backscatter coefficient is
a fundamental ultrasonic property that has been used to characterize many tissues …

From an acoustical point of view, bone is a complex medium as it is heterogeneous,
anisotropic and viscoelastic. This chapter reviews the basic notions of physical acoustics …

This paper reviews theory, measurements, and computer simulations of scattering from
cancellous bone reported by many laboratories. Three theoretical models (binary mixture …

The goal of this study is to model the frequency dependence of the ultrasonic backscatter
coefficient in cancellous bone. A twofold theoretical approach has been adopted: the …

The measurement of broadband ultrasonic attenuation (BUA) in cancellous bone at the
calcaneus was first described in 1984. The assessment of osteoporosis by BUA has recently …
