Cone-based electrical resistivity tomography [PDF]

open access: yesGeophysics, 2006
Abstract Determining the 3D spatial distribution of subsurface properties is a challenging, but critical, part of managing the cleanup of contaminated sites. We have developed a minimally invasive technology that can provide information about the 3D distribution of electrical conductivity.

Convergence and regularization for monotonicity-based shape reconstruction in electrical impedance tomography [PDF]

open access: yes, 2016
The inverse problem of electrical impedance tomography is severely ill-posed, meaning that, only limited information about the conductivity can in practice be recovered from boundary measurements of electric current and voltage.
