Modelling of Ultrasonic Backscattering from Discrete Random Scatterers
A comprehensive model of the scattering of ultrasound is used to calculate the backscattered pressure from two-dimensional arrays of cylindrical scatterers approximating the structure of muscle tissue.
Regular arrays of identical scatterers and random arrays of scatterers varying only in their radii are treated. First attempts at simple data analysis for these cases are described.
One of the effects of muscular dystrophy is a change in the propagation velocity of sound in the muscle cells. To model this situation, arrays of scatterers with different propagation velocities are considered and it is shown that even a small change in the velocities for muscle can change the echo pattern considerably.
