Abstract: To solve the ‘soft-field’nature and the ill-posed problem in electrical capacitance tomography technology，a Huang clan correction image reconstruction algorithm for electrical capacitance tomography is presented. Firstly，according to the basic principles of the Electrical Capacitance Tomography system，the formula of Huang clan correction in the problem of capacitance tomography is derived. Secondly，the iterative formula for simulation experiment is given after the correction. Finally，the validity of the proposed method is verified by digital simulation. The simulation experiment results show that the error of the image for extremely low layer flow，low layer flow and core flow dropped to 24. 39% ，25. 81% and 40. 91% respectively. Ｒesults were lower than Linear Back Projection method，Landweber method，Steepest Descent method and Conjugate Gradient method. In addition，the number of iterations were maintained at 12，12 and 27times，also less than the Landweber method and the Steepest Descent method. The results of the analysis show that the effect of the Huang Clan Correction Image Ｒeconstruction Algorithm are good
