Abstract:

The ultrasonic attenuation occuring at the cell-level structure of blood due to absorption of cells, relative viscous motion of cells to the plasma and the sound scattering by cells is discussed in this paper.The theoretical prediction is well confirmed by experimental data.The analysis shows that in the contribution to the ultrasonic attenuation by the cellular structure of blood,the absorption of cells is of most importance, the part of viscous loss is below 15% and the sound scattering of cells is negligible.
