Abstract

From the electrical potential captured at the perimeter of the cross section of an object (collected by placing electrodes), an Electrical Impedance Tomography (EIT) system must be able to estimate a distribution of conductivities within this section, in a noninvasive way. The quantity of measurements captured by the hardware is related to the quality of the final reconstructed image. A firmware capable of determining phase and amplitude difference with different electrode and frequency configurations will be developed.
