Development and Study of Image Reconstruction Algorithm for Electrical Capacitance Tomography

In order to realize measurement on line for multi-phase flow parameter using electrical capacitance tomography (ECT), it is the key to improve quality and rate of image reconstruction, which also is hot spot for researcher. In this paper, ECT image reconstruction algorithms are reviewed by their principle and recently researches on image reconstruction are introduced. The most commonly used ECT image reconstruction algorithms, LBP, Landweber iteration, MLRR were evaluated using simulations. Future possibilities on ECT image reconstruction algorithms are also discussed.
