Abstract :
Microwave ablation has several medical applications including liver, kidney, bone and lung. Numerical simulation of microwave ablation is a step in the implementation of system design. This paper presents the temperature distribution of targeted radiation dipole antenna for microwave ablation at 2.45GHz. This experiment through the temperature profile around the antenna achieves in the range 50W, 60W and 70W. In addition, we set the ablation time in the range 300s,600s and 900s. The goal of this work is to develop a device for directional tumor ablation avoiding destruction of neural structures.
