Abstract

This article describes the design of an electrical impedance tomograph (EIT), with the aim to provide a tool to detect morphological changes in tissues. This design consists of an array of 16 electrodes distributed on a ring way. The 4 points technique is used to record the amplitude of the electrical impedance. The array was placed around of a tank filled with a saline solution and objects of different sizes and shapes as test material. The operation of the system is controlled by a program developed on LabVIEW, the impedance data recorded are sent to a MATLAB toolbox called EIDORS to be processing. The final result is a reconstructed image in witch objects larger than 1 cm of contrasting impedance can be recognized.
