FIG. 8.

Matched B mode and ARFI images on the lesion phantom. The left side is the B-mode image and the right side is the maximum-displacement image calculated from ARFI dataset. The units of the axes are mm. In the B-mode image, the lesion-to-background contrast is 35.4% while it is 83.7% for the ARFI image. The contrast values were calculated based on the gray values within the area defined by the dashed box.
