Abstract
In hyperthermic oncology, the disease is treated by applying localized heating to the tumor, usually in combination with chemotherapy or radiotherapy. Heating is provided to the tumor from the part where a thin microwave antenna is placed. Here, a coagulated area is produced where cancer cells are killed. In this study, the temperature change, tissue deformation and specific absorption rate (SAR) of the tissue under the microwave effect were calculated. The liver tissue was modeled with a coaxial slot antenna at a frequency of 2.45 GHz and a numerical solution was made in the Comsol program. Result simulations of tissue after 2-4 and 6 minutes were obtained by taking different microwave powers (10-20-30W). It has been seen that the results obtained are compatible with the literature information.
