Deep seated superficial tumors cannot be heated adequately with existing hyperthermia systems. This study investigates the use of a new flexible double waveguide design for hyperthermia of these treatment sites. The proposed set-up consists of two opposing rectangular 70 MHz waveguides. The aperture size of the bottom antenna was 20×34cm and three different interchangeable top antennas with aperture size 20×34cm, 15×34cm and 10×34cm were proposed to allow appropriate tumor coverage at any location. Simulations in a homogeneous phantom and a patient anatomy were performed. Phantom results showed that good SAR coverage is possible with all three antenna combinations. Simulation for the patient anatomy confirmed that adequate heating of deep superficial tumors is possible with the proposed design.
