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...
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...
The purpose of this research reported here is to evaluate an abnormal finger motion of trigger finger using Leap Motion Controller to measure finger joint angles by the dot product equation. This sensor is 3D non-contact motion sensor which can detect finger bones. It is estimated positions and directions for fingers and bones. Four postures are used to evaluate an abnormal finger motion that has...
This research proposes a design of a novel microwave applicator which encapsulated in fluid reservoir for a thermal therapy. Heat generated from microwave energy is applied to cure or to reshape a hollow-tubing shape organ or misshape organ from occlusion or narrowing such as tracheal and benign prostatic hyperplasia. This promising technique provides a shorter treatment time and minimal invasive...
Lung cancer or pulmonary cancer is one of a dangerous cancer threatening human life since a long time ago. Even though, a conventional surgery is widely accepted as a gold standard for this cancer treatment, however a new medical maneuver still be investigated to perform with this disease. In this paper, we trail a simulation of thermal ablation by using microwave energy at 2.45GHz, 30 Watts for 10...
This paper presents a concept of the design and development of an infant incubator by increasing a number of an air flow slot for air-inlet and air-outlet inside a double wall infant incubator. The number of airflow inlet slot is increase to 2 while an airflow outlet slot is to 4 at the lateral side. The study is done by using FEM simulation to compare between single air flow slot and multi air flow...

And to compare the results of heat transfer measurements from experiments on the IRW in used everywhere. In this study, results are obtained for a simplified model. It is equipped with. Systems design, the properties of materials...
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...
Bone drilling by using heat energy from microwave is a promising research issue and has been proposed by some researcher. However, there are still some interesting topics remaining to be investigated especially in term of a temperature variation during burning or drilling process and a prediction of an extreme burning size or drilling diameter. In this paper, we propose an FEM investigation of bone...

The purpose of this research is to study the effects and harmfulness of leakage electromagnetic field to organ in living tissue. We propose a simulation of microwave radiation by using a finite element method (FEM) to our system for studying...
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...
This paper presents heat transfer from infrared element source from infant radiant warmer. The principles of thermal radiate using three-dimensional finite element methods is show the efficiency and effect of Infant radiant warmer. In the design of the system has to model the underlying reality of the infant radiant warmer are used for Simulation results were similar to reality as possible. The simulation...
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,...
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 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...
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...
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...
Microwave ablation for liver cancer treatment has been widely performed due to its minimal invasive technique both single and multi probe. Even though, multi antenna ablation system provide a larger destroy area, however effect of phase shift difference between each antenna is still challenge to be investigate for total ablation result. In this research, we propose a preliminary investigate of phase...
Breast cancer is one of the main health hazard that threatening women life all over the world. Not only her own daily life, but also her own family whom suffering from this poor fate. Besides from a breast resection, microwave ablation is also another effective therapeutic technique for glandular tissue cancer treatment due to its minimal invasive maneuver. In this paper, we propose a study of an...
