【Abstract】 Research on the electrical characteristic of two-dimension head model through a new type of medical image reconstruction technology, which is called Electrical Impedance Tomography (Eli), has been presented. The forward problem is solved by finite element method and the method of simple back projection is adopted to reconstruct the image. The result is consistent with the real model.更多还原
