Abstract

We have derived equations relating to the cumulants of the backscattered signal to material and transducer parameters. Then, we proposed a practical method to estimate the material grain moments from estimates of the cumulants at some particular values. The proposed model and techniques are verified on some phantoms having different scatterer density and grain sizes.
