Abstract :
As a measure technology for testing parameters of multi-phase flow, electrical capacitance tomography (ECT) has the characteristics of non -intrusion, non -radiation, low cost, fast response, easy to implement. The quality and rate of image reconstruction are critical for application of ECT in practical industries. In this paper, the factors including numberof pixel, shape of finite element, number of electrode sensor and the permittivity turbulence that affect the reconstructed image quality have been analyzed using Linear Back Project (LBP) algorithm, Landweber Iteration and Multiple Linear Regression and Regularization(MLRR). The analysis results are helpful to the parameters design of image reconstruction in capacitance tomography for improve the image quality.
