Three Dimensional Electrical Impedance Tomography [PDF]
Nature, 1996 The electrical resistivity of mammalian tissues varies widely and is correlated with physiological function. Electrical impedance tomography (EIT) can be used to probe such variations in vivo, and offers a non-invasive means of imaging the internal ...

Electrical impedance tomography [PDF]
Annals of Translational Medicine, 2018 Continuous assessment of respiratory status is one of the cornerstones of modern intensive care unit (ICU) monitoring systems. Electrical impedance tomography (EIT), although with some constraints, may play the lead as a new diagnostic and guiding tool for an adequate optimization of mechanical ventilation in critically ill patients.

Optimal transportation for electrical impedance tomography
Mathematics of Computation, 2023 This work establishes a framework for solving inverse boundary problems with the geodesic-based quadratic Wasserstein distance ( W 2 W_{2} ). A general form of the Fréchet gradient is systematically derived from the optimal transportation (OT) theory.

Acousto-electrical speckle pattern in Lorentz force electrical impedance tomography [PDF]
, 2015 Ultrasound speckle is a granular texture pattern appearing in ultrasound imaging. It can be used to distinguish tissues and identify pathologies. Lorentz force electrical impedance tomography is an ultrasound-based medical imaging technique of the tissue

Fuzzy modeling of electrical impedance tomography images of the lungs
Clinics, 2008 OBJECTIVES: Aiming to improve the anatomical resolution of electrical impedance tomography images, we developed a fuzzy model based on electrical impedance tomography's high temporal resolution and on the functional pulmonary signals of perfusion and ...

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

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

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
