Abstract

In this study, we developed a simple instrumentation for electrical impedance tomography (EIT). In general, EIT systems have the following components: a system with electrodes, a current source and a current drive and voltage measurement system. In this work, we utilized a cylindrical container with six rectangular electrodes, a resistor-based current source and an Arduino micro-controller for the drive and measurement system. EIT experiments were done on a dalandan and angular analysis was performed to investigate and quantify the accuracy of the image reconstructions via image processing techniques. The results show a deviance of 0.15 radians between the real and reconstructed images. This relatively small error indicates the good accuracy of the EIT system in reconstructing the object.
