Figure 2.
Raw ultrasound backscattered signals and the corresponding envelope signal can be used to estimate Nakagami parameter m to model the statistical distribution of backscattered-signal envelope R.
Different Nakagami parameters indicate different envelope statistics caused by different properties of scatterers in the tissue.
