Abstract

Reconstructed images produced using Electrical Impedance Tomography (EIT) are notorious for their poor spatial resolution. This is largely due to the ill-posed nature of the EIT problem. Much effort has been made in order to improve on spatial resolution of reconstructed images. One of the more direct approaches is by improving the amount of information obtainable. With the development and transition from 2D to 3D tomography, more measurements can be obtained to better inform the inversion problem through expanding the number of electrodes or through measurement strategies. This paper delves into the latter method, providing a comparison study using sensitivity analysis, stability of measurement analysis and spatial resolution analysis, with the aim of providing a better understanding of the influence of varying different parameters on the quality of reconstructed images, before more unconventional methods of increasing information through unconventional measurement strategies are devised. © 2013 IEEE.
