Comparison of (A) marked M-mode image with corresponding (B) macroscopic lesion image for HIFU exposure with the lower intensity of 2600 W/cm2, 1 kHz PRF, 50% duty cycle, and 1 s exposure time. In the M-mode data, the vertical dashed red lines indicate the times at which the HIFU treatment was turned on and off (t = 0.2 s and 1.2 s). The yellow box vertically delineates the estimated spatial region where the lesion was formed based on examination of the macroscopic lesion and horizontally delineates the temporal duration from 0.5 s to 0.7 s after the HIFU was turned off. In the macroscopic lesion, the yellow vertical dashed line indicates the approximate location of the M-mode line, while the dashed horizontal lines show the correspondence between the M-mode and macroscopic lesion along the lesion boundaries. The inset B-mode image is shown at 40% scale to the macroscopic images.
