Abstract

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.
