Journal ArticleDOI

Identification of a suitable current waveform for acute stroke imaging

TL;DR: The purpose of this work was to find the most suitable current pattern that could be employed in MFEIT measurements in the adult head with the UCLH Mk2.5 system, which applies currents from 20 Hz-1.6 MHz.
Journal ArticleDOI

Evaluation of a multi-electrode bioimpedance spectroscopy tensor probe to detect the anisotropic conductivity spectra of biological tissues

TL;DR: The current pattern for localized electrical energy concentration, performance with the spring loaded pin electrodes, data calibration and experimental results on anisotropic agar phantoms and different tissue types are described.
Journal ArticleDOI

A Local Region of Interest Imaging Method for Electrical Impedance Tomography with Internal Electrodes

TL;DR: A local ROI imaging method with internal electrodes developed from careful analysis of the sensitivity matrix is proposed that convincingly shows an improvement in local sensitivity in images obtained with an internal electrode in comparison to a standard reconstruction method.
Journal ArticleDOI

Code-Division-Multiplexed Electrical Impedance Tomography Spectroscopy

TL;DR: The method described provides images and spectra which are equivalent to the conventional time-multiplexed method, with increases in frequency resolution and measurement speed which may be of benefit in some applications of electrical impedance tomography spectroscopy.
