Figure 20From: Estimating dynamic changes of tissue attenuation coefficient during high-intensity focused ultrasound treatmentLesion growth in ex vivo porcine muscle tissue in Δ α 0 images during slow HIFU experiment. 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.Back to article page
