Heating control method of resonant cavity applicator for non-invasive hyperthermia treatment

This paper describes a heating control method of the resonant cavity applicator for brain tumor hyperthermia treatment. In this study, we proposed several heating control method. In the first method, the diameters of the inner electrodes are changed. In addition, the position of the phantom between the inner electrodes was changed. In the second method, the dielectric bolus was used. The bolus is attached to the human head and is filled with dielectric materials, such as pure water, saline and so on. By changing the dielectric properties inside the bolus, heated region can be controlled. From these results, it was confirmed that proposed methods are useful for treating brain tumors.
