Figure 7From: Estimating dynamic changes of tissue attenuation coefficient during high-intensity focused ultrasound treatmentΔ β images detecting lesions in ex vivo porcine muscle tissues at 10 min posttreatment. The duty cycle was 77%, resulting in TAP values of 34, 37, 39, 44, and 49 W, for HIFU treatment time of 40 s. A total of four lesions were created at every power level.Back to article page
