A review of antenna designs for percutaneous microwave ablation
نویسندگان
چکیده
Microwave (MW) antenna is a key element in microwave ablation (MWA) treatments as the means that energy delivered focused manner to tumor and its surrounding area. The results rise temperature lethal level, resulting cell death zone. delivery of hence success MWA closely dependent on structure antennas. Therefore, three design criteria, such expected zone pattern, efficiency delivery, minimization diameter antennas have been focus along evolution MW antenna. To further improve performance treatment various tumors through inventing novel antennas, this article reviews state-of-the-art summarizes development designs regarding criteria.
