Original Abstract

This scientific paper deals with the development of an analogue-digital card for electrical impedance tomography. The aim of the paper is to address the problems of measuring impedance, frequency and excitation current levels, and measured voltage, which are crucial for the efficient reconstruction of inhomogeneity distributions using electrical impedance tomography. The paper presents the design of an active probe system to suppress interference and increase sensitivity in impedance measurements. This design is based on the use of signal amplifiers and the switching of reference measurement electrodes. Experimental results show the high accuracy and sensitivity of the newly developed system. These results suggest that the new system can be used to improve systems in various disciplines of non-destructive diagnostics.
