Abstract:

Microwave cancer therapy is an effective method used to destroy cancer cells which eliminates the need for surgical intervention in diseases such as breast and liver cancer. The present study aims to present a methodology for the destruction of killing the malignant cells in a wider periphery by means of burning in a shorter time meanwhile causing minimal damage to the healthy tissues. The study is carried out for a frequency value of 2.45 GHz and for a power value of 10 W using finite element methods. A comparison between coaxial single-slot antenna and double-slot antenna is conducted for liver and breast tissues. Investigated parameters are the slot number, the type of the tissue and the duration of microwave cancer therapy. The specific absorption rate and temperature distribution are the examined parameters. The results of the study show that both peak specific absorption rate and peak temperature value are obtained for microwave coaxial single slot antenna within the liver tissue, and it is observed that the temperature distribution depends on time. Maximum temperature value is attained as 93.9oC and 82.8oC for single and double slot antennas for liver tissue whereas the so-called values are 93.0oC and 69.8oC for breast tissue. New correlations are given for the treatment of liver and breast tissues using coaxial single slot antenna. It is anticipated that the present study makes a contribution in the field of medicine.
