Abstract :
A modified model of ultrasound scattering, based on the structure of biological tissues, is derived. It assumes that the scale of elastic modulus fluctuation of tissues is statistically distributed. The results explain the observed variation of the backscattering coefficient with frequency for a number of tissues
