Forward Problem of Three Dimensional EIT in Thorax Model

The forward problem of the three dimensional electrical impedance tomography is presented in thorax model. Here potential distribution on the edge of the model measuring plan can be gotten by finite element method. The potential distributions of inhaling and exhaling models are shown, and the opposite drive pattern are adopted with single drive current or multiple drive current. The forward problem is the base of the inverse problem in EIT research, and it is helpful to the monitor on thorax activities.
