Ultrasonic Absorption Measurement of a Model of Fatty Liver Tissue

Conference paper


The principal properties involved in ultrasonic tissue characterization are the speed with which the wave propagates and the absorption of the wave energy. Absorption is a material parameter, as it does not include the scattering and reflection properties included in the attenuation parameter. It is important that we obtain ever more absorption data of bio-materials in order to have a complete understanding of the interaction of ultrasound and living materials. Many studies of the ultrasonic analysis of tissues have been reported [1]-[11]. Here, analysis means that we have a material of unknown properties, and we wish to determine its characteristics. In the field of electrical engineering, for example, we also consider studies of “synthesis” of materials. First, analysis studies may be conducted, which lead to synthesis studies. The continuation of the processes leads to a deeper understanding of the media structure and to superior models. Thus, we think in terms of the synthesis of a model which has properties similar to that of human tissues, from which it may be expected that research on the origin of ultrasound absorption will be improved.
