This paper presents the effect on potential distributions and current streamlines for Electrical Resistance Tomography (ERT) applying metal wall pipe. A conducting boundary approach was applied in the measurement part of the research and COMSOL Multiphysics software has been applied in this work to solve the forward problem of the system. Sixteen electrodes with gold plated material as the conducting surface and FR4 as the insulating material were implemented as the sensing plate in the research. The simulations showed that the sensing field will be deflected based on the conductivity distribution within its sensing region. The electrical potential of the system also varied accordingly.

Tomography system is a method that being used to reconstruct a cross sectional image in vessel or pipeline. This method is widely used in medical and industrial fields. The aim of this paper is to provide an overview of tomography system based on its basics construction, types of sensors, its applications in today’s industry, and image reconstruction. This paper review consists of literature citations which related with tomography system.
