Microwave Ablation Multi-Antennas Operation studying for Hepatic Cancer Microwave Ablation Treatment system using 3D-Finite Element Analysis

Abstract

In our country, many people need appropriate treatment from hepatic cancer. Most of them still get the traditional method treatment which is high cost and too risky. Microwave ablation treatment is used microwave heat to eliminate cancer which is one of the other choices. However, it still needs to limit the area of heat dissipation. To prevent microwave heat destroy other organs. So, this research intends to present the analysis of double antenna variable setting and microwave system designing for appropriated heat to eliminate hepatic cancer by 3D finite element analysis in vitro experiment pattern. In the experiment, the open-tip antennas will be used and placed in parallel. The experiment will study the appropriate determination of each antenna switching time and power transmitting value. Moreover, there is an experiment with other two different types of antenna, slot, and slot with insulating jacket. The result shows that double antennas with different operating time and power cause heat to destroy hepatic cancer cells which can determine the size and has a geometric shape as desired. This technology can be applied to the treatment of hepatic cancer that has an asymmetrical shape.
