    ¡¾Abstract¡¿ AIM: To find the value of the realª²time biplane imaging in observing the dynamic changes of percutaneous microwave coagulation in freshly dissected dog¡¯s liver. METHODS: Different microwave power (40 W, 50 W, 60 W and 70 W) and time (60 s, 80 s, 100 s, 120 s, 140 s and 160 s) were used to coagulate freshly dissected dog¡¯s livers and the microwave antenna was guided by traditional ultrasound and the dynamic process was lively observed by realª²time biplane ultrasound imaging. RESULTS: The local coagulation area was lively observed from two different angle planes by the realª²time biplane ultrasound imaging and the pathological slice, no significant difference was found in the coagulation size measured by the two methods biplane (P>0.05). CONCLUSION: The realª²time biplane ultrasound imaging can lively observe the process of percutaneous microwave coagulating in freshly dissected dog¡¯s liver from two different angels. ......
