From: Small-window parametric imaging based on information entropy for ultrasound tissue characterization
(a) B-mode and (b–e) entropy images of Type-II simulated phantoms containing strong scatterers with different RSCs constructed using different SLs. (b) SL = 1; (c) SL = 2; (d) SL = 3; (e) SL = 4. The dimensions for all images are the same. The grayscale and color bars represent the pixel values (the brightness) of the B-mode and entropy images, respectively. The change in the shade of the entropy images showed a decrease in the entropy because of the increasing phantom inhomogeneity.
