Electrical resistance tomography with voltage excitation

2016 IEEE International Instrumentation and Measurement Technology Conference Proceedings, 2016
Electrical Resistance Tomography (ERT) has been widely accepted as a useful tool to visualize conductivity distributions. Traditional ERT systems use a scheme with current injection and voltage measurement to detect changes in conductivity in a region of interest.

Electrical Resistance Tomography imaging of concrete

Cement and Concrete Research, 2008
We apply Electrical Resistance Tomography (ERT) for three dimensional imaging of concrete. In ERT, alternating currents are injected into the target using an array of electrodes attached to the target surface, and the resulting voltages are measured using the same electrodes.

Reconstruction techniques for electrical resistance tomography

IEEE Transactions on Magnetics, 2000
The unknown resistivity of a bounded conductive body is retrieved starting from boundary measurements in stationary conditions. A new nonlinear inversion procedure following a critical analysis of the well-known Newton-Kantorovic method is proposed. The wavelets compression capabilities are used to reduce the number of parameters needed to describe the

Coupling Simulation for electrical resistance tomography

2016 IEEE International Conference on Imaging Systems and Techniques (IST), 2016
The performance of electrical resistance tomography (ERT) system is usually investigated by numerical simulation or static tests using some simple phantoms. The objective of this paper is to construct a coupling simulation model for ERT. In this model, the distribution information of multi-phase flow is exchanged between the fluid field and electric ...
