High-Precision Electrical Impedance Tomography for Electrical Conductivity of Metallic Materials
Advances in Materials Science and Engineering, 2022 Metal materials are subject to deformation, internal stress distribution, and cracking during processing, all of which affect the distribution of electrical conductivity of the metal. Suppose we can detect the conductivity distribution of metal materials

A mathematical and numerical framework for ultrasonically-induced Lorentz force electrical impedance tomography [PDF]
, 2014 We provide a mathematical analysis and a numerical framework for Lorentz force electrical conductivity imaging. Ultrasonic vibration of a tissue in the presence of a static magnetic field induces an electrical current by the Lorentz force.

A multiscattering series for impedance tomography in layered media [PDF]
, 1999 We introduce an inversion algorithm for tomographic images of layered media. The algorithm is based on a multiscattering series expansion of the Green function that, unlike the Born series, converges unconditionally.

Approximation of full-boundary data from partial-boundary electrode measurements [PDF]
, 2017 Measurements on a subset of the boundary are common in electrical impedance tomography, especially any electrode model can be interpreted as a partial boundary problem. The information obtained is different to full-boundary measurements as modeled by the
