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

Thirty-eight slices of pure trabecular bone 1-cm thickness were extracted from human
proximal femurs. A pair of 1-MHz central frequency transducers was used to measure …

The present study was designed to assess the relationships between QUS parameters and
bone density or microarchitecture on samples of human femoral trabecular bone. The …

An understanding of the interaction between acoustic waves and cancellous bone is needed
in order to realize the full clinical potential of ultrasonic bone measurements. Scattering is …

The technology surrounding ultrasonic bone assessment is evolving rapidly as investigators
explore the utility of new ultrasonic parameters and different ultrasonic frequencies. This …

Ultrasonic measurements were made in three orthogonal directions on 70 vertebral bone
cubes. Apparent density (ρ) was determined, and microcomputed tomography was used to …

Apparent integrated backscatter (AIB) is a measure of the frequency-averaged (integrated)
backscattered power contained in some portion of a backscattered ultrasonic signal. AIB has …

Ultrasonic propagation in bone has been investigated using the Leeds Ultrasonic Bone
Phantom Material. Phantoms were produced with different porosities in the range of 45 …

Ultrasound parameters (attenuation, phase velocity, and backscatter), bone mineral density
(BMD), and microarchitectural features were measured on 29 human cancellous calcaneus …

Multichannel pulse-echo ultrasound using linear arrays and single-channel data acquisition
systems opens new perspectives for the evaluation of cortical bone. In combination with …
