Uncertainties Analysis of Electrical Resistivity Tomography
2021<p>We examined the uncertainty of the resistivity method in cavity studies using a synthetic cavity model set at six-different depths. Conceptual models were simulated to generate synthetic resistivity data for dipole-dipole, pole-dipole, Wenner-Schlumberger, and pole-pole arrays.

Analysis of Sensitivity Matrix for Electrical Resistance Tomography
2019 IEEE International Instrumentation and Measurement Technology Conference (I2MTC), 2019Electrical Resistance Tomography (ERT) is a detection technique for reconstructing conductivity distribution from boundary measurements. However, the image reconstruction of ERT is an ill-posed and nonlinear inverse problem. There are many algorithms for solving inverse problems based on the sensitivity theory, the basic idea of which is to use the ...

Crossâborehole electrical resistivity tomography
SEG Technical Program Expanded Abstracts 1990, 1990Tomographic imaging (Hounsfield, 1974) has revolutionized medical X-ray diagnostics and is now a valuable technique in many areas of science. In geophysics, tomographic images have been constructed from both seismic and electromagnetic measurements (Anderson and Dziewonski, 1984; Dines and Lytle, 1979).

Regularization Parameter considering Electric Field Attenuation for Electrical Resistance Tomography
2020 IEEE International Instrumentation and Measurement Technology Conference (I2MTC), 2020Electrical resistance tomography (ERT) is widely used to reconstruct internal conductivity distribution of the measured field from the boundary data. The inverse problem of ERT is seriously ill-posed and nonlinear. Tikhonov regularization method is a well-known method to solve the problem.

Electrical resistance tomography for process applications
Measurement Science and Technology, 1996Measurement of electrical resistivity via four probes is widely used in a variety of applications ranging from geophysical prospecting to silicon wafer manufacture. Electrical resistivity tomography is an extension of this approach and is performed via an array of equi-spaced electrodes mounted into the periphery of a process vessel to map non ...

QERT - Quadrupole Electrical Resistivity Tomography
2020<p><span>The quadrupole technique for geoelectrics yields the apparent resistivity in a tensorial form in contrast to the scalar apparent resistivity obtained from classical geoelectrics. The quadrupole method in geoelectrics has been applied in the past only for long offsets between transmitter and receiver.
