%X To solve the soft-field nature and the ill-posed problem in electrical capacitance tomography technology, on the ba-sis of combining the least squares method and iterative algorithm, this paper presented a least squares image reconstruction al-gorithm restricted by iterative method for electrical capacitance tomography. Presented a mathematic model for the algorithm and proved its convergence characteristic, this image reconstruction algorithmmade the iteration step was optimal on the prem-ise of convergence. Experiment results and simulation data indicate that the algorithm is more stable and the precision of image is higher compared with least squares method, and presents a feasible and effective way to the research of image reconstruction algorithms for electrical capacitance tomography system.
