A 32-electrode data collection system for electrical impedance tomography

IEEE Trans Biomed Eng. 1995 Jun;42(6):632-6. doi: 10.1109/10.387203.

Abstract

A 32-electrode data collection system for Electrical Impedance Tomography (EIT) will be presented. In this system, the demodulator is a multiplexed sample and hold (S&H) circuit followed by a voltage difference stage. This configuration provides high CMRR due to the low (almost DC) operating frequency of the signals the difference stage is required to process.
