Many iterative reconstruction algorithms for electrical impedance tomography have been proposed and tested using simulated data. A comparison between measurements and the simulated model has found that there is a significant difference. This prevents the reconstruction from giving meaningful practical results. By modifying the conventional iterative reconstruction algorithm, the difference has been reduced so that reasonable reconstructions can be obtained from the measured data.
