Electrical Impedance Tomography

SIAM Review, 1999
A mathematical model for electrical impedance tomography is described. This model is used for explaining the Rensselaer system. Some reconstruction algorithms are surveyed, especially the Moser algorithm. Some experimental tests are given.

Electrical Impedance Tomography

Current Opinion in Critical Care, 2009
Electrical impedance tomography (EIT) is a noninvasive, radiation-free monitoring tool that allows real-time imaging of ventilation. The purpose of this article is to discuss the fundamentals of EIT and to review the use of EIT in critical care patients.In addition to its established role in describing the distribution of alveolar ventilation, EIT has ...

Electrical impedance tomography

IEEE Signal Processing Magazine, 2001
Electrical impedance tomography (EIT) is an imaging modality that estimates the electrical properties at the interior of an object from measurements made on its surface. Typically, currents are injected into the object through electrodes placed on its surface, and the resulting electrode voltages are measured.

Electrical impedance endotomography

Physics in Medicine and Biology, 2002
In electrical impedance endotomography (EIE), the impedance measuring electrodes are placed at the centre of the region of interest instead of encircling it, as in usual electrical impedance tomography. EIE has been developed for prostate imaging. The developed mathematical model enables the derivation of analytical equations for electric potential ...

Imaging the complex impedance in electrical impedance tomography

Clinical Physics and Physiological Measurement, 1992
Measuring the reactive component of the bio-impedance enables a full characterisation of the frequency response of a tissue. The amplitude of the reactive component is relatively small in the frequency range generally used in electrical impedance tomography (EIT). Its measurement is therefore more sensitive to errors.

Electrical impedance of the pituitary gland

Journal of Neurosurgery, 1970
✓ Experimental and clinical measurements of electrical impedance revealed a significant well-delineated difference between the pars distalis and the pars nervosa, providing an accurate and easy means of identifying the tissue interface between these two elements of the pituitary gland.
