Hyperthermia is a method of treatment of oncological diseases by means of increasing tumor’s temperature up to 40…43°C. Hyperthermia isn’t applied alone but usually like adjunct to the established treatment methods such as radiation and chemotherapy. High temperature of tumor cells makes its more sensitive to the radiation and to the anticancer drugs. Creating of high level temperature distribution in the tumor site by the phased array of applicators was proposed. Varying phases and amplitudes of each dipole provides focusing electromagnetic energy in the deep situated tumors. It is very important to save healthy tissues from overheating. Prediction and control of temperature distribution inside the patient body is a significant part of the treatment process. The planning system for the thermoradiotherapy procedure is under development. Numerical simulation methods of the E-field and temperatures distributions produced by the phased array are described. These simulation techniques use a finite-element method. Resulting distributions of E-field and temperature are also presented.
