Abstract :
An alternative interstitial hyperthermia system using thin flexible electrode wires operating at 27.12 MHz has been developed, and an 8-channel apparatus has been evaluated. Its major benefit is its potentializing effect, which is obtained without affecting radiation therapy techniques. It is possible to match the electrode to any kind of catheter implantation used for radiotherapy (even in a loop). Major advantages of this method are radial and longitudinal uniformity of heating, free choice of active length for each electrode, flexibility, and compatibility with the implanted radiotherapy catheters
