A Three-dimensional Phantom for Evaluating the Performance of Electrical Impedance Tomography System

Abstract

Electrical impedance tomography is an imaging technology based on the impedance characteristics of the measured object. In this paper, a three-dimensional phantom is studied to verify and evaluate 3D EIT systems. The conductivity distribution can be changed by tuning the resistance values. Simulation results show that the proposed phantom can be used for 3D EIT imaging.
