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 ...

Lorentz Force Electrical Impedance Tomography [PDF]

IRBM, 2013
This article describes a method called Lorentz Force Electrical Impedance Tomography. The electrical conductivity of biological tissues can be measured through their sonication in a magnetic field: the vibration of the tissues inside the field induces an

Electrical Impedance Tomography: the future of mechanical ventilation?

Journal of Mechanical Ventilation, 2021
Electrical Impedance Tomography is a rapidly evolving technology used for bedside lung imaging. Although EIT devices have been commercially available for the past decade, they are still not commonly used in everyday clinical practice.

Electrical impedance tomography in pulmonary arterial hypertension.

PLoS ONE, 2021
The characterization of pulmonary arterial hypertension (PAH) relies mainly on right heart catheterization (RHC). Electrical impedance tomography (EIT) provides a non-invasive estimation of lung perfusion that could complement the hemodynamic information

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.
