Contrast Improvement in Sub- and Ultraharmonic Ultrasound Contrast Imaging by Combining Several Hammerstein Models
Figure 6
(a) Comparison between the signal backscattered by the contrast agent (in black) and its estimation (in green): the signal modeled with (top) the standard Hammerstein model, (middle) method 1, and (bottom) method 2. (b) Spectra of different signals presented in (a). Here dB.
