Fig. 5From: Detection of tissue coagulation by decorrelation of ultrasonic echo signals in cavitation-enhanced high-intensity focused ultrasound treatmentB-mode images of the tissue a before the start, b immediately after the start, and c end of HIFU exposure and d differential B-mode image between c and b. The propagation direction of HIFU is from left to right. The HIFU focal point was 50.0 mm in depth and 12.5 mm in width, which was measured with the needle hydrophone in waterBack to article page
