Lesion growth in ex vivo porcine muscle tissue in conventional B-mode images during slow HIFU. The slow HIFU experiment was conducted with a duty cycle of 77% and TAP of 5 W, resulting in an average focal intensity of 117 W/cm2 at the HIFU treatment site, for a total HIFU treatment time of 9 min and 39 s. B-mode images were obtained continuously from the beginning of treatment to the end of treatment.
