Electrical impedance endotomography
Physics in Medicine and Biology, 2002In 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, 1999A 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, 1992Multifrequency 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, 2005We 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.

Impedance and electric modulus spectroscopy is exploited over a broad frequency and temperature range to find the relaxation phenomenon in LaFeO3 (LFO), which otherwise was concealed by the dc conductivity in dielectric ɛ*(ω) representation.

Electrical impedance tomography
IEEE Signal Processing Magazine, 2001Electrical 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.
