“…Concerning the use of the FEM, although some groups have developed their own software [ 23 , 24 ], most have employed commercially available software. For instance, most RF ablation models have used ANSYS [ 17 , 28 , 30 , 41 - 45 , 48 , 53 , 62 , 92 ] since it is able to perform electrical-thermal coupled field analysis with temperature-dependent properties. However, the main disadvantage of ANSYS is its cost.…”

Radiofrequency ablation is an interventional technique that in recent years has come to be employed in very different medical fields, such as the elimination of cardiac arrhythmias or the destruction of tumors in different locations. In order to investigate and develop new techniques, and also to improve those currently employed, theoretical models and computer simulations are a powerful tool since they provide vital information on the electrical and thermal behavior of ablation rapidly and at low cost. In the future they could even help to plan individual treatment for each patient. This review analyzes the state-of-the-art in theoretical modeling as applied to the study of radiofrequency ablation techniques. Firstly, it describes the most important issues involved in this methodology, including the experimental validation. Secondly, it points out the present limitations, especially those related to the lack of an accurate characterization of the biological tissues. After analyzing the current and future benefits of this technique it finally suggests future lines and trends in the research of this area.

“…Clinical experience shows that large blood vessels near the ablation domain reduce the size of the lesion by transporting thermal energy away from the domain [1,4]. The influence of a 4-mm diameter blood vessel near the proximal end of a single needle probe on the temperature distribution in the tissue was studied in a 2-D model by placing the blood vessel perpendicular to the probe.…”
