An Analytical Solution for Radiofrequency Ablation with a Cooled Cylindrical Electrode

Figure 1

(a) Physical situation modeled: an RF applicator is inserted in the tissue and the active electrode is placed in the center of a spherical tumor. (b) Analytical model has one dimension () and a domain from (active electrode radius) to (where the dispersive electrode is assumed to be placed). The active electrode is in the middle of a tumor of radius , and consequently the healthy tissue occupies a region between and .
