Abstract
Efficient ablation with multiple prong electrodes is obtained by electrically isolating the prongs from each other and rapidly switching electric power between the prongs, between a prong and a ground pad, or both. In this way, power distribution to a tumor can be controlled efficiently without the need to change probe geometry.
