    Example of Structure Modeling and Analysis of Ultrasound Scattering for Trabecular Bone by Janusz WÓJCIK, Jerzy LITNIEWSKI, Andrzej NOWICKI

    Published 2013-11-01
    “…A trabecular bone consists of trabeculae whose mechanical properties differ significantly from the surrounding marrow, therefore an ultrasonic wave propagating within the bone structure is strongly scattered. The aim of this paper was to evaluate the contribution of the first, second and higher order scattering (multiple scattering) into the total scattering of ultrasound in a trabecular bone. …”
