Theoretical analysis of sound attenuation mechanisms in blood and in erythrocyte suspensions.
A theoretical analysis of the effect of the elasticity of cell membranes on sound attenuation in blood and erythrocyte suspensions was carried out. It is shown that the shell model of a cell adequately describes the attenuation in red blood cell suspensions. The contribution of viscous drag losses to the sound attenuation decreases with frequency, and at a frequency of 1 MHz it can be as high as 44% in water suspensions of erythrocytes and 24% in blood.
