Popis:	We consider the simulation of thermal and electrical processes, involved in a radio-frequency ablation procedure. Radio-frequency ablation is a low invasive technique for treatment of hepatic tumors, utilizing AC current to destroy unwanted tissues by heating. We simulate an ablation procedure where the needle is bipolar, i.e. no ground pad is attached. Saline solution is injected through the needle during the procedure, creating a cloud around the tip with higher electrical conductivity. This approach is safer for some patients.
