ABSTRACT
Electrical Impedance Tomography (EIT) is a noninvasive, painless, and ionizing radiation-free technique
for image acquisition of a region of interest. It is performed through electrical parameters. The method
is based on the application of an alternating electric current pattern of low intensity through electrodes
arranged around the surface region in order to obtain the image and also to measure the excitation
electrical potentials. The aim of this study is to develop a device based in open hardware. Furthermore,
the authors aim to build a prototype of a data acquisition system based on EIT. This device is the frst
step to obtain a complete and portable tomography equipment at a low cost.
