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.

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.
