Previously it has been demonstrated that cortical bone thickness can be estimated from ultrasonic guided-wave measurements, in an axial transmission configuration, together with an appropriate analytical model. This study considers the impact of bone

Quantitative ultrasound (QUS) transmission and backscatter measurements were made in 46 human cancellous bone specimens from the calcaneus. All QUS measurements were made at 35°C, initially with marrow filling the pores and then repeated after subst

Measurements of broadband ultrasound attenuation (BUA) on a single sample using different devices have previously shown significant variations. We have used a new 3x3 array transducer to allow the evaluation of three new approaches to the BUA algorit

This study evaluated two different approaches to the prediction of Young's modulus (E) from ultrasonic velocity and density measurements in 23 cubes of cancellous bone from human calcaneae. The first approach used clinically applicable measurements o

The aim of the present study was to investigate the prediction of vertebral and femoral strength in vitro by bone mineral density (BMD) measured at different skeletal sites. The third lumbar vertebral body, the right proximal femur, and the right cal
