Fig. 2.

(Color online) STL-SWEI of uniform tissue-mimicking phantoms. Shown are representative B-scan and overlaid color images of shear modulus estimates of phantoms under different configurations. (A) A large uniform, gelatin phantom imaged as in Fig. 1(A). (B) A smaller gelatin phantom (sectioned from the large phantom) placed in a tissue culture plate imaged as in Fig. 1(B). (C) The smaller gelatin phantom was removed from the tissue culture plate and submerged in a water tank and imaged. (D) The smaller phantom was placed at an angle and imaged. (E) STL-SWEI performed at the interface between the water and larger phantom. Images are representative of three separate samples. Scale bar, 4 mm.
