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

Current Opinion in Critical Care, 2012
Electrical impedance tomography (EIT) is a useful noninvasive tool for monitoring ventilation finding its way into the clinical setting. The focus of this review is to discuss the balance between the potential for EIT as a clinical monitor accepting a level of uncertainty and the scientific demand for absolute perfection.The controversy concerning ...

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 ...

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.

Multifrequency electrical impedance tomography

Clinical Physics and Physiological Measurement, 1992
Multifrequency tomography may be conveniently achieved by sequentially sweeping the probing drive current and measuring the resultant voltages at each frequency. If events change during measurement comparisons between frequencies cannot be made. Mixing several frequency components may decrease acquisition time but increase the complexity of the ...

Non-contact Scanning Electrical Impedance Imaging

The 26th Annual International Conference of the IEEE Engineering in Medicine and Biology Society, 2005
We are interested in applying electrical impedance imaging to a single cell because it has potential to reveal both cell anatomy and cell function. Unfortunately, classic impedance imaging techniques are not applicable to this small scale measurement due to their low resolution.
