One-dimensional computer simulation of a wave incident on randomly distributed inhomogeneities with reference to the scattering of ultrasound by blood

To further the understanding of the complex problem of scattering of ultrasound by blood the authors present a computer simulation of a simpler onedimensional analogue. Blood is modelled as a row of scatterers of constant thickness, separated by random intervals with a sinusoidal wave incident upon the row. The variation of backscattered power with haematocrit follows qualitatively that found experimentally by other workers for a suspension of erythrocytes in plasma. The model also indicates a large standard deviation of backscattered power analogous to that observed in blood.
