This paper presents an analysis of heat sink effect in hepatic cancer treatment near arterial vessel for microwave ablation by using finite element method. We analyze the temperature distribution, Specific Absorbtion Rate (SAR) and coagulation area in two models. The first is hepatic tissue without artery and the second is hepatic tissue with artery. In the second model, we specify distance between...
This paper presents three-dimensional finite element method for analyze a varicose vein microwave ablation. Varicose vein can contract by using heat from microwave ablation. Because of varicose vein patients have leg pain from long time standing, and do a lot of activities. Symptoms have influenced the daily life of patients. We study method for varicose vein therapy by using microwave ablation. Because...
This paper presents three-dimensions finite element analysis of 2.45 GHz microwave ablation for plagued coronary artery treatment. Any narrowing or blockage of the coronary arteries reduces blood supply to the heart tissue, following by reducing an amount of delivered oxygen and nutrients. This phenomenon inhibits a normal function of the heart muscle. In this research, we propose an application of...
This paper presents analysis of asymmetry slot antenna configuration for microwave ablation at 2450 MHz using three-dimensional finite element analyses treatment for liver tissue. We designed new coaxial-slot antenna is opened slot at one-side of antenna. We study heat transfer for liver tissue by used MW Ablation system, varying the angle of open slot at 90°, 180°, 270° and 360°. The results illustrate...
This paper reports a novel three-dimensional finite element analysis of coaxial antenna for hepatic microwave ablation. We analyses the temperature distribution pattern and lesion size on hepatic cancer of cap-choke antenna at frequency of 2.45GHz. We set duration time for microwave ablation in the range 60s, 100s, 200s and 300s. We set the potential difference between the inner and an outer conductor...
