Contrast Improvement in Sub- and Ultraharmonic Ultrasound Contrast Imaging by Combining Several Hammerstein Models
Figure 8
Variation of RMSE in dB between the backscattered signal by the contrast agent and that modeled with (blue) the standard Hammerstein model, (black) method 1, and (green) method 2 as a function of the memory of Hammerstein model in presence of output noise: dB, dB, dB, and dB.
