            Fig. 3: RF electrode was accurately placed into the tumor, without puncturing the nearby blood vessel (under the ultrasonic guidance)


























                         Fig. 4: The tip of the needle was advanced under ultrasound guidance to the proximal edge of the lesion





















                                  Fig. 5: The curved electrodes were advanced step-by-step to full deployment
