Determination of the Parameters of Cancellous Bone Using High Frequency Acoustic Measurements Ii: Inverse Problems
In a precursor to this article the Biot model was used to model poroelastic media. The question this article addresses is whether the sort of experiments described by McKelvie and Palmer, Williams, and Hosokawa and Otani can be used to determine the parameters of the Biot model. A method of computing acoustic pressure in the low 100 kHz range was developed in Buchanan and Gilbert, “Determinatio...
متن کاملDetermination of the parameters of cancellous bone using high frequency acoustic measurements
The Biot model is widely used to model poroelastic media. Several authors have tested its applicability to cancellous bone, but to do so requires a priori estimation of the parameters of the Biot model, which is an uncertain and expensive endeavor. The question this article addresses is whether the sort of experiments described by these authors in fact can be used to determine the parameters of...
متن کاملAcoustic Properties of Cancellous Bone and Evaluation of Bone Density
The propagation of both fast and slow longitudinal waves in bovine cancellous bone in vitro was experimentally examined by the pulse transmission technique in relation to the bone density. Experimental results show that the propagation speed and the amplitude of the fast wave increase greatly with the bone density and those of the slow wave decrease reversely with the bone density.
متن کاملCorrelations between acoustic properties and bone density in bovine cancellous bone from 0.5 to 2 MHz.
Correlations between acoustic properties and bone density were investigated in the 12 defatted bovine cancellous bone specimens in vitro. Speed of sound (SOS) and broadband ultrasonic attenuation (BUA) were measured in three different frequency bandwidths from 0.5 to 2 MHz using three matched pairs of transducers with the center frequencies of 1, 2.25, and 3.5 MHz. The relative orientation betw...
متن کاملDetermination of sediments diameter using acoustic waves
The use of acoustic waves in researches related to sea water is of most importance among scientists recently. Since these waves are the only waves, transmitted in water with lowest attenuation and high speed, they can be used in many scientific fields. The main goal of this research is to better understand the physics and mechanisms of sound-seabed interaction, including acoustic penetration, p...
