Abstract

This paper presents a novel approach to an electrical impedance tomograph’s system and hardware architecture design. It delves into the strategic decisions that shaped the hardware layer of a measurement system comprising multiple units and enabling intercommunication between them. The primary objective was to develop a cost-effective method for switching a current source among numerous electrodes and measuring voltage across each with a wide dynamic range while maintaining a minimal phase shift between the channel and input of an analog-to-digital converter. The measurement system is designed and documented, serving as a valuable reference for developing new additional units.
