Abstract :
This work describes an analytical method to find the conductivity distribution in Electrical Impedance Tomography (EIT). The new method leads to a faster algorithm that is expected to increase the speed of obtaining EIT images. First results were obtained in a phantom made of graphite paper. The measurements were carried out with 16 electrodes and a DC current
