Item type:Publication, FEM modeling for performance evaluation of microwave ablation applicator when using T prong monopole antennas(2015-01-01); This paper present three-dimensional finite element method (3D FEMs) simulate of temperature distributions in liver cancer tissue. This study focuses on the evaluation of the performance of a T Prong Monopole Antennas. The configurations of monopole antennas were considered: Two-prong Monopole (2PM), Three-Prong Monopole (3PM) and Equilateral Four-Prong Monopole Antenna (4PM). The 3D FEMs solutions were based on Maxwell and bio-heat equations for studying 2.45GHz T Prong monopole antenna design. We apply the microwave power was 20 W; the duration time for ablation in all case was 300s. From our simulation results, all antennas type have occurred the hotspot at the tip of prong of the antenna. Two-prong Monopole antenna can be induced the highest temperature in cancer tissue. Thermal distributions were obtained and compared. The results indicate that the Two-prong Monopole antenna generated maximum temperature within liver cancer tissue and can be maximum ablation cancer tissue (5.94 cm3). The temperature distribution is determined by the direction of bifurcation of the antenna. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, 3D finite element analysis for varicose vein therapy by using microwave ablation(2012-12-01); ; ; Sanpanich, A.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 of this method is easy to use for varicose vein therapy. In this research work, we propose simulation varicose vein that varicose vein is inserted with antenna into blood vessel. Simulation method delivers microwave to antenna inserted in varicose vein. For this reason, varicose vein is contract. Finite element analysis can apply in treatment planning and show temperature distribution and specific absorption rate (SAR) distribution for contract of varicose vein characteristic by using microwave therapy. And the doctor can be use the data for treat in future. ©2012 IEEE. - Some of the metrics are blocked by yourconsent settings

Item type:Publication, Optimal antenna slot design for hepatocellular carcinoma microwave ablation using multi-objective fuzzy decision making(2020-10-01); ; Chayakulkheeree, KeeratiThis paper presents the optimal antenna slot position and sizing (OASPS), for microwave (MW) hepatocellular carcinoma (HCC) treatment, using multi-objective fuzzy decision making (MOFDM). In the optimal design problem formulation, the multi-objective for, (1) achievement for a near-spherical zone for ablation defined by axial ratio (AR), (2) the minimum reflection coefficient (S11), and (3) maximum volume of destroying (VD), are desired. The finite element method (FEM) is used for MW distribution simulation for coordination analysis with the proposed MOFDM based OASPS. The investigation on the design results shown that the temperature distribution of the proposed MOFDM for OASPS is in the more controllable shape comparing to the existing design, due to the sharp beam of temperature distribution to the target at the front side of slot with the less temperature distribution at the rare side of slot. The results also show that the proposed MOFDM for OASPS for OASPS design is easier to manage with the less effect to the rare side of the slot. Moreover, the proposed MOFDM for OASPS resulted in the temperature distribution shape closer to round shape than the existing design. The MOFDM for OASPS is tested on designing of the antenna build up from the coaxial cable. The coaxial cable used is Semi-rigid 141 (RG402 M17/130-RG402 Copper Jacket) including Inner conductor, Dielectric, and Outer conductor. In the simulation, the slot distance from conductor end (Lts), representing the slot position, is varied as 2.3mm, 3.3mm, 4.3mm, 5.3mm, 6.3mm, 7.3mm, and 8.3mm. Meanwhile, the slot size (Wd), is varied as 1mm, 2mm, 3mm, 4mm, 5mm, and 6mm. The input power (Pi) used is 50 W with the duration of 300 seconds. The comparison of obtained by different L<inf>ts</inf> and W<inf>d</inf>, is investigated. The simulation results show that the proposed MOFDM based OASPS can efficiently and effectively provide the near-spherical zone of ablation result with simultaneously trade-off between S11 minimization and VD maximization. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, In vitro practical evaluations on heating characteristics of thin microwave antenna in maximum temperature control mode(2015-01-01); Microwave thermal therapy is one of the modalities for cancer treatment. There are several schemes of microwave heating. The authors have been studying thin Coaxial Quarter Conductor Antennas (CQCA) for intracavitary microwave heating aiming at the treatment of hepatic cancer. Experimental protocol was composed by a radiation microwave power system and a thermometry system. We apply the microwave power during experiments was 10W, 20W, 30W, 40W, 50W, 60W, 70W and 80W which we set the maximum temperature control at 90°C for all case Experiment, Thermal sensors were placed next to the antenna at 1mm, a large number of experiments on porcine liver are carried out, the temperature distribution within the porcine liver are measured, for cases of different injected microwave power. Experiment for finding a possibility of the treatment. In this study, in order to consider practical situations of the treatment, heating characteristics of the antenna inserted into sample tissue. Moreover, the relation between coagulation size of the tissue, the radiation power from the antenna and the volume of lesion which the hepatic cancer was successful hepatic ablation. From these investigations, some useful results for practical treatments were found. - Some of the metrics are blocked by yourconsent settings
