WebUltrasound attenuation spectroscopy has found wide application in the study of colloidal dispersions such as emulsions or suspensions. The main advantage of this technique is that it can be applied to relatively high concentration systems without sample preparation. In particular, the use of Epstein-Carhart-Allegra-Hawley’s (ECAH) ultrasound … WebDec 1, 2011 · When broadband ultrasoundpropagates through bone, it loses some of its energy due to attenuation. The attenuation appears to vary linearly with frequency ( Langton et al. 1984 ), in which the slope of the attenuation curve is called broadband ultrasound attenuation (BUA).
WebAn ultrasound transmission scanning system was constructed to makein vivo parametric images of the acoustic properties of the heel.
