Figure 4

Parametric images at different times during the HIFU treatment of R3. The first, second, and third columns of the sub-figures represent B-mode images, parametric B-mode images enhanced by ΔEAC, and curves of the temperature and average ΔEAC versus time of exposure, respectively. The red circles indicate the time points corresponding to the displayed B-mode and parametric images. The three rows in the figure represent the results at three different time points of 23, 79, and 116 s, respectively, during the exposure. HIFU = high-intensity focused ultrasound; EAC = effective acoustic concentration.
