Abstract
|
|
|
|
There have been many studies on the impedance characteristics of body tissues for decades. Since the breast tissue is relatively uniform compared to other tissues and the electrical characteristics of normal and tumor tissues are obviously different, for the breast cancer detection the electrical impedance method seems to be promising. The purpose of this research is to investigate the feasibility of the detection of a cancerous tissue in a normal tissue with a numerical method based on the finite element method and to design the electrode configuration. The effect of the skin tissue having high permittivity on the measurement of the electrical signals have also been studied. The results of this study can be used as the fundamental data for the development of the electrical impedance method for the beast cancer detection.
