Resistivity Imaging of a Phantom with Irregular Inhomogeneities with 16 Copper Electrodes Based Sensory System in 2 Dimensional Electrical Impedance Tomography



In this paper, the fabrication of 16-copper electrode based electrical impedance tomography (EIT) system is fabricated. EIT is a tool for imaging the interior permittivity distribution of an object (stone/tumor) by measuring voltage at the surface. This method is useful for detecting the shape, size and position of unwanted lumps within a specified area. In order to understand the proposed work, a simulation study using Finite Element Method (FEM) based Multiphysics software has been performed, in which we have imaged perfectly the shape, position and sizes of both the regular and irregular shaped objects situated within a specified phantom area in a 2D plane. Simultaneously, we have developed a real-time system consists of 16 copper electrodes (placed equidistantly) detect non-conducting like plastic container in normal saline solution. We have injected a constant current to the phantom boundary and the surface potentials are being measured using neighbouring method. We have collected the output data sets and reconstructed the voltage density distribution plot using FEMM tool. The resulting images show that the resistivity profiles of the phantom for various events are successfully observed.
