Abstract. Radiofrequency ablation (RFA) is a minimally invasive way to treat cancer. The main problem of RFA is insufficient heating volume. The aim of the work is to create new electrode systems to improve heating characteristics by increasing the number of electrodes operating in bipolar mode. Studies were carried out on a four-channel installation ‘METATOM-3’. The number of dual electrodes varied from 1 to 8. The results of thermal fields obtained with such electrode systems are presented. Potato, whose structure changes when heated up to 60°C, was used as a simulator of biological tissue for the first time, which allows visualising the volumetric picture of the thermal field. To investigate the temperature distribution in the heating volume, a thermal imaging study of the tissue simulators was also carried out. It was found that the increase in the number of electrodes and transition to bipolar mode make it possible to eliminate the need for switching and increase the uniformity of the resulting heating, which is evident from the results of thermal imaging study.
Key words: radiofrequency ablation, thermal imaging, simulator, potato, bipolar mode, electrode, tumour.
