Part of the Acoustical Imaging book series (ACIM, volume 10)


The scattering coefficient of blood, χ, is usually very low in the MHz range. However, it is significantly increased for blood samples with high sedimentation rate (ESR) values. A detailed account is given on the derivation of χ from A. mode echo-graphic signals.Then, it is related to the organization of the erythrocytes (RBC) in the blood, through a simplified statistical model. The mean number of RBC per aggregate can thus be determined.

Experimental results on the value of the backscattering coefficient are given: correlation with the theoretical model for the hematocrit dependence, studies on high ESR samples, studies on artificially aggregated samples.
