The Electrical Impedance Tomography(EIT)is divided into the static state EIT(The imaging target is the absolute value of the distributing of Electrical Impedance)and dynamic EIT(The imaging target is the relatively value of the distributing of Electrical Impedance relatively value).It's comparatively popular imaging technology in the study of biomedicine engineering at home and abroad in recent years.Compared to the present imaging technique of X-ray,computer section scanning (CT),MRI and ultrasonic,this new technique has not only the anatomy information but the character of functional imaging.It has a beautiful applied foreground in clinic application for its characters such as its character of non-invasion,simple,low cost and easy use.By using math,physics,and its new application at home and abroad,this paper gives an instruction of the math computation of the(ETI),the prindple of physics,as well as the basic principle of EIT and its clinic application.
