Figure 3: Simulated entropy as a function of the number density of the scatterers obtained at different SLs.
From: Small-window parametric imaging based on information entropy for ultrasound tissue characterization
(a) SL = 1; (b) SL = 2; (c) SL = 3; (d) SL = 4. Entropy images constructed using windows of different sizes can detect the variation in the number density of scatterers in a homogeneous medium. Data were expressed by mean ± standard deviation.
