The elastic properties of bone tissue determine the biomechanical behavior of bone at the organ level. It is now widely accepted that the nanoscale structure of bone plays an important role to determine the elastic properties at the tissue level. Hen

Ultrasonic evaluation of coarse-grain materials generates multiple scattering at high frequency and large depth. Recent academic experiments with array probes showed the ability of a random matrix method [multiple scattering filter (MSF)] to reduce m

We report on ultrasonic imaging in a random heterogeneous medium. The goal is to detect flaws embedded deeply into a polycrystalline material. A 64-element array of piezoelectric transmitters/receivers at a central frequency of 5 MHz is used to captu

Ultrasonic non-destructive testing of polycrystalline structures can be disturbed by scattering at grain boundaries. Understanding and modeling this so-called “structural noise” is crucial for characterization as well as detection purposes. Struc

ATHENA2D is a finite element code dedicated to the wave propagation simulation. The good agreement between experimental and simulated data necessitates the use of accurate input data. Generally the input data are provided by experimental measurements

Ultrasonic non destructive testing of coarse-grain materials can be hampered by backscattered noise. Recent laboratory studies on synthetic samples have shown that the contribution of single scattering could be separated from multiple scattering, by
