Design of an interstitial capacitive hyperthermia system operating at 27.12 MHz

The authors suggest an alternative interstitial method operating at 27.12 MHz. Physically, the system is essentially capacitive and the heating is induced by the conduction current between the 'hot' electrode and the ground plane. Thermographic results obtained with a two-channel homemade apparatus are presented. The simplicity and low cost of the technology, the possibility of tailoring the electrodes to the geometry and the tumor site, and the radial and longitudinal uniformity of the heating represent the major advantages of this method. A commercial prototype with eight electrodes is presented.<>
