Phase dependent EIT

Frontiers in Optics 2007/Laser Science XXIII/Organic Materials and Devices for Displays and Energy Conversion, 2007
We study the EIT of Rb vapor under the condition when a microwave field resonant to the hyperfine transition has been applied. Developed theory and applications will be discussed.

Simultaneous Acquisition of EIT and ECG Signals on Active EIT Electrodes

IEEE Transactions on Biomedical Engineering
This paper introduces a new method of simultaneous acquisition of electrocardiogram (ECG) signals and electrical impedance tomography (EIT) measurements on active electrodes, i.e. electrodes that are applying current, in an EIT system.Howland noise reduction followed by an integrate-and-dump filter and adaptive filtering are used to extract the ECG ...

A multifrequency serial EIT system

Physiological Measurement, 1996
A multifrequency (1 kHz-1 MHz) serial electrical impedance tomography (EIT) system has been developed. It is based on 16 active electrodes and can be extended up to 32. Each active electrode can be programmed for current driving and for measuring either the injected current or the voltage difference between adjacent electrodes, and includes calibration

Noise equalization within EIT images

Physiological Measurement, 1994
We first describe experiments designed to measure the spatial distribution of noise within an electrical impedance tomographic image of a saline-filled tank. These experiments show that the noise increases by a factor of up to 30 from the periphery towards the centre of the image.

Euura eiteli ZMUO.

237 Euura eiteli (Saarinen, 1948) Figs 260, 496 Amauronematus eiteli Saarinen, 1948: 82–83. Diagnosis Females have more or less the same nearly completely or mostly pale orange colouration as E. longiserra and most E. neglecta, but the serrulae of E. eiteli are almost flat (distinctly more protruding in E.
