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
