Macroscopic and echographic visualzation of HIFU ablated area.

HIFU ablations were clearly visible in ultrasound images. Dimensions measured on sonograms were correlated to the dimensions measured on gross pathology. (a) Typical HIFU ablation observed on gross pathology, (b) on sonograms obtained with the integrated ultrasound imaging probe (IUSP) of the HIFU device and (c) on sonograms obtained with a higher resolution ultrasound imaging probe. (d) Correlation between dimensions measured on sonograms using IUSP and gross pathology.
