Figure 16From: 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. The duty cycle was 77%, resulting in TAP of 49 W and average focal intensity of 1,068 W/cm2 at the HIFU treatment site, for a total HIFU treatment time of 40 s.Back to article page
