TL;DR: The ultrasonic axial transmission technique, used to assess cortical shells of long bones, is investigated using numerical simulations based on a three-dimensional (3D) finite difference code and it is shown that the cortical depth that contributes to lateral wave SOS measurement is approximately 1-1.5 mm under classical in vivo measurement conditions.

TL;DR: This work focuses on the apparent speed of sound (SOS) of the first arriving signal (FAS) and its dependence on the thickness of the plate, which depends on both the time criterion and on the source-receiver distance.

TL;DR: This work investigated the relationships between low-frequency axial transmission sound speed at 1 and 2 MHz, structural properties (cortical width Ct.Wi, porosity, Haversian canal density) and material properties (acoustic impedance, mineral density) on site-matched cross-sections using a 50-MHz scanning acoustic microscope and synchrotron radiation microcomputed tomography.

TL;DR: This work investigated, in vitro, the relationships between 1‐MHz axial transmission SOS measurements at the radius and site‐matched measurements of C.Th, POR, MIN, and vBMD.

TL;DR: The results suggest that NRUS could be a potential tool for micro-damage assessment in bone and further work must be carried out for a better understanding of the physical nature of damaged bone.
