Abstract

An orthogonally rotated radiating array applicator is proposed to enhance the therapeutic suitability of superficial hyperthermia treatment system. The proposed applicator provides an optimal heating effect to widely distributed tumors by configuring the orthogonal arrangement of radiating elements. Each element causes a destructive interference of electromagnetic field at the center of the array applicator, so as to prevent an overheating at the central region. The electric field and the specific absorption rate (SAR) are evenly formed with a circular-shaped distribution, which allows for the uniform heat deposition on the therapeutic area. The achieved ETA ratio is 152.6 %, corresponding to 44 % increase, as compared with the single element operation. The proposed hyperthermia applicator not only leads to a wide therapeutic coverage by the orthogonally rotated array configuration, but it also satisfies the thermal requirement for tumor necrosis.
