One of the main problem which threatening health in middle-aged women around the world is breast cancer. Not only a physical painfulness but also including her own family and victim relatives who suffering from this unavoidable pity fate. To detect those cancerous tumors as in an earlier stage as possible seem to be the best way to handle with this hazard. Besides from x-rays mammography and a conventional diagnostic ultrasound, microwave radiation tomography technique is a promising method to investigate any abnormality forming in her mammalian gland. In this paper, we propose a simulation of microwave radiation using a finite element method (FEM) of our modified imaging setup system for female breast cancer diagnosis. By using FEM, we propose a preliminary study of microwave breast cancer detection from a patch antenna propagation in 3D tissue space approaching. In term of wave penetration, voluminous 3D distribution geometry of electrical field in nonhomogenous simple breast phantom model was presented. These simulations not only show a promising result but also encourage us to develop a real imaging setup system in the near future. © 2011 IEEE.

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 antenna and artery at 10 mm. The initial condition is set as power at 50 watts, temperature at 37°C and blood perfusion rate is varied at 6.4 × 10-10, 6.4 × 10-3 and 6.4 × 104 l/s. The simulation results by using three-dimensional finite element analysis show that the temperature distribution in case of hepatic tissue with no artery is larger than the case with artery. We also found that blood perfusion rate affects to the temperature distribution in hepatic tissue. Higher blood perfusion rate, higher heat sink effect occur. ©2012 IEEE.

Pulmonary microwave ablation has been trailed and became dramatically recognized as an alternative surgical method for lung cancer treatment due to its minimal invasive technique and destroyable only a small part of malignant tissue. Even though, lung is realized as a porous tissue in which filled of humid air and a capillary network that rather difficult to control an ablation region, then a prediction of lung destructive region by using MWA simulation seem to be a reliable investigation and numerical tool for supporting this medical maneuver. In this paper, we propose a simulation of microwave thermal ablation for lung cancer treatment in a simple lung model. Microwave applicator was designed as an opened-tip coaxial antenna of 2.45 GHz at 10 Watts. To study an effect of air flow in pulmonary bronchus, a small tube with air flow was also placed close to the microwave applicator then a temperature distribution and coagulation volume at 60 °c were analyzed. The in silico results show a predictable ablation shape which affected by a convection heat transfer of a humid air. However, before a real ablation with swine tissue, an amount of pulmonary blood flow in small blood vessel should be also included in the next investigation inorder to obtain more reasonable results.

This paper presents a study of heat transfer efficiency in double wall infant incubator by using 3D finite element method. Double wall infant incubator was modeled by using general CAD program then FEM analysis was implemented based on heat transfer and fluid dynamic principle. Real temperature measurement also performed to validate our simulation by using a general infant incubator and an infant incubator analyzer. Real experimental data at each 4 monitoring points and simulation data provide a small difference in temperature. In the future work, infant model should be included into our incubator in order to estimate a heat source effect from newborn baby. ©2012 IEEE.

In a respiratory failure patient, an artificial ventilation is commonly performed by using a mechanical ventilator particularly in an ICU ward. On such a case, an endotracheal tube (ETT) must be inserted into patient's airway and following by a balloon cuff blowing in order to fix and act as a sealed artificial airway for an artificial ventilation. However, those implementations adversely affect to tracheal tissue-epithelial layer and probably damaging a larynx and vocal cord zone. After a ventilator weaning and an extubating process, some patients always suffering with a larynx or tracheal edema symptom or postextubation stridor (PES) in which patient airway is narrowed or swelling due to a long term pressurization by the ETT balloon cuff. This mainly causes a difficulty in a spontaneous breathing. In general, a cuff leak test is a common medical maneuver used in order to predict a larynx or tracheal edema possibility after ETT was removed. Air volume different between an inspired volume (Vtì) and an expired volume (Vie) normally should be higher than 100 mL or 10%. In this paper, we propose an investigation of an airflow pattern on an intubated patient in the cuff leak test process in order to understand and support a prediction of the tracheal edema before perform an ETT extubation. The study was performed in an intubated trachea by using a simulation of an airflow pattern, air volume prediction in a normal intubated case and during cuff leak test process with no edema and edema case. Although, this simulation was intently implemented in a simple intubated trachea model, however the obtain results imply us a practical information and will be used as a basic implementation for a further study, especially in case of variety in the ETT intubation or cuff less ventilation even more complication case in the near future.

This study presents an optimal location of monitoring point for using by PID system to control temperature and output power of hepatic cancer microwave ablation system. We investigated a relation between output power and treatment time in hepatic ablation. A simple simulation model was adapted from COMSOL FEM solver. As a preliminary, monitoring point was supposed to place at 0.5 centimeter besides ablation probe. The simulation results shown that temperature at this monitoring point is linearly related to output power and treatment time. ©2012 IEEE.

The research aimed to present airflow analysis of radiofrequency ablation for asthma therapy by using three-dimensional finite element method. We study a solution for asthma therapy by using radiofrequency ablation method. Airflow is main factor for asthma therapy. Asthma patients have shortness of breath, coughing, wheezing, and chest tightness that influence a daily life of patients. All symptoms cause to die, especially in severe symptom patients. Asthma therapy by using radiofrequency ablation is a new alternative maneuver to the patient and hopefully may extend his lifetime, reduce using of medicines in asthma treatment and also save money on medical care. The simulation results obtained from our three-dimensional finite element method show airflow that will directly affect the temperature distribution by using radiofrequency ablation technique. These simulation results also guide us to develop an advance asthma treatment in the future. © 2013 IEEE.

Thermal ablation by using energy from an electromagnetic wave in microwave and radiofrequency range is widely accepted as an alternative therapeutic maneuver for an internal cancer treatment as a breast tumor. However a comparison study between these two techniques are still an interesting topic especially in term of main control parameters, output and outcome of an expect coagulation zone. In this research, we propose a comparison investigation of microwave and radiofrequency ablation in a breast phantom model by using FEM. Our breast model is originally and specially designed as a multi-layer tissue in order to close to a real human breast organ. The simulation results show an interesting different output from these two EMW frequencies as an ablation power, treatment time and also coagulation area significantly. ©2012 IEEE.

This paper presents a three-dimensional finite element analysis for severe asthma therapy by using radiofrequency (RF) ablation. We study a solution for severe asthma treatment by using radiofrequency ablation method. Severe asthma patients have breathlessness symptom, coughing, and wheezing that influence a daily life of patients. In case of severe asthma, patients have breathlessness symptom, coughing, and wheezing all the time. All symptoms cause to die. Severe asthma therapy by using radiofrequency ablation is a new alternative maneuver to the patient and hopefully may extend his lifetime, reduce using of medicines in asthma treatment and also save money on medical care in long run. The research results obtained from our three-dimensional finite element analysis show temperature distribution for airway dilation and increasing airway wall dimension by using radiofrequency ablation technique significantly. These results also guide us to develop an advance asthma treatment in the future. ©2012 IEEE.
