The Factorization Method for Electrical Impedance Tomography Data from a New Planar Device
The Factorization Method Electrical Impedance Tomography
2009/9/7
We present numerical results for two reconstruction methods for a new planar electrical impedance tomography device. This prototype allows noninvasive medical imaging techniques if only one side of a ...
Frequency-Division Multiplexing for Electrical Impedance Tomography in Biomedical Applications
Frequency-Division Multiplexing Electrical Impedance Tomography Biomedical Applications
2009/9/7
Electrical impedance tomography (EIT) produces an image of the electrical impedance distribution of tissues in the body, using electrodes that are placed on the periphery of the imaged area. These ele...
Reproducibility and repeatability of measuring the electrical impedance of the pregnant human cervix-the effect of probe size and applied pressure
the electrical impedance the pregnant human cervix-the effect probe size applied pressure
2010/2/25
Measuring cervical resistivity by a single observer with both the 3 and 12 mm probes is highly repeatable whilst inter-observer reproducibility is poor with the 3 mm probe but moderately good when the...
An Optimal Spot-Electrodes Array for Voltage Pick-Up Determined from the Measurement of Transthoracic Electrical Impedance Change Following Cardiac Ejection
impedance or admittance cardiography cardiac output stroke volume optimal spot-electrodes array
2009/6/2
Electrical impedance (or admittance) cardiography is a simple and still potential method for non-invasive and continuous monitoring of stroke volume and cardiac output (CO) by detecting the electrical...
Comparison of human uterine cervical electrical impedance measurements derived using two tetrapolar probes of different sizes
human uterine cervical electrical impedance measurements two tetrapolar probes different sizes
2010/2/26
Inter-electrode distance on the probes for measuring cervical impedance influences the tissue resistivity values obtained. Determining the appropriate probe size is necessary when conducting clinical ...

tomography system an open access circuit design
2010/2/26
The results of simulation and real measurement of the system are presented. The reconstruction programs were written in MATLAB and the data acquisition software in C++. The system has been tested with...
Electrical impedance tomography imaging using a priori ultrasound data
Electrical tomography imaging a priori ultrasound data
2010/2/26
This paper discusses the combination of ultrasound and electrical impedance tomography (EIT) information. Ultrasound reflection signals are good at locating sharp acoustic density changes associated w...
Review of "Electrical Impedance Tomography" Edited by David S. Holder
Electrical Impedance Tomography David S. Holder
2010/3/1
As implied by its name, electrical impedance tomography (EIT) is to reconstruct an impedance distribution in an object of interest from electrical measurement on the boundary of the object. Because of...
