Abstract
A series of applicators has been developed on the basis of phased array (PA) for electromagnetic high-frequency hyperthermia and simultaneous radiation therapy of tumors characterized by high transparency to gamma radiation. The resistance of the main material of the microstrip emitter and its array against ionizing radiation has been studied. A possible seven dimensions of PA applicators operating at a frequency of 434 MHz have been considered. The distribution of the squared electric component of the electromagnetic field emitted by an applicator in the plane of the applicator aperture, the SAR (specific absorption rate) has been measured. The experimental results of the SAR distribution in the plane of the applicator aperture from single modules for electromagnetic exciting fields differing in phases are presented. The main parameters of the Quality Standard in oncological hyperthermia have been considered, which should be achieved in the treatment of oncological patients with the specific list of nosological forms of neoplasms.
