The aim of this paper was to propose a novel approach to the ultrasound (US) characterization of human bones through an improved measurement of the apparent integrated backscatter (AIB). Four intact human femoral heads were studied ex vivo in their physiologic morphological configuration, including cartilaginous, cortical and trabecular regions. Each sample underwent an US acquisition performed with...
The purpose of this work was to study the relationships between quantitative ultrasound (QUS) parameters and the microstructure properties of human proximal femur samples. QUS data acquisition was achieved by means of a custom-developed experimental set-up, which allowed the insonification of excised femoral heads along 30 different directions, each time including both the trabecular region and the...
