Abstract :
In this contribution, we illustrate the performance of the developed UWB microwave hyperthermia system in combination with the treatment planning tool based on time-reversal algorithm. The experiment comparing the temperature distribution in muscle-equivalent phantom with the predicted SAR pattern was carried out at the ISM radio frequency 434 MHz. The obtained results have shown an excellent agreement between planned and measured data in terms of the correct focusing and iso-SAR countours.
