| Popis: | The success of the radiofrequency ablation (RFA) in treating liver has shown great success. Recently, greater successes are achieved however without its challenges. Possible side effects after ablation therapy include abdominal pain, infection in the liver, and bleeding into the chest cavity or abdomen. The mathematical expression for the conversion of sound to heat energy was used to investigate the conductive transference of heat energy from the ablation zone to the surrounding tissues. We considered two groups of probes and the maximum energy available for transfer. It was discovered that probing technique is capable of releasing heat energy of 120 J for each probe from each ablation zone. This omission is very critical for clinical processes. For above ten ablation zones, enormous transference of energy to the neighboring tissues is further enhanced by the differential tissue impedance. Hence, there is more danger when excess tissue impedance is imposed on the ablation zones. |
