Ablation lesion size as a function of the separation time of the HIFU treatment cycle. At intensities of (A) 140, (B) 390, and (C) 650 W/cm2, no statistically significant differences were observed between the volumes of the ablation lesions at separation times of 2, 4, and 6 s for any given insonation time (n ≥ 4, mean ± S.D.).
