Phantom Based Analysis and Validation using Electrical Impedance Tomography

Abstract

Electrical impedance tomography offers an inexpensive and portable measurement instrument for monitoring of electrical conductivity for medical and industrial type phantom. This paper presents a simple hardware of EIT system and experimentation on different phantoms, through this system. The number of electrodes may be used is 4, 8, 16, 32, etc. and they can be used according to requirement and diameter of the object. But the selection of a high number of electrons, obtains higher resolution and more clarity of the image. In this paper, we have used 16 and 8 number of electrodes; and also presented a graph for each phantom accordingly to our experimental study of phantom/object.
