Four Element Computer Controlled 432 MHz Phased Array Hyperthermia System
A phased array hyperthermia system using four applicators has been developed to treat tumors at mid-depths from the body surface. The operation frequency is 432 MHz. The system consists of four independent but otherwise fully coherent channels. The applicators are water loaded waveguide cavities of 2.9 × 5.8 cm2 aperture. In order to model the system and to operate it as a phased array system electromagnetic and optimization theory techniques have been used.
