摘要进行了电容层析成像(ECT)三维图像重建的仿真研究。首先利用COMSOL软件对ECT传感器进行三维建模,基于其高精度的有限元求解,计算ECT的灵敏度矩阵;其次,基于Matlab软件实现了基于线性反投影(LBP)及Landweber迭代算法的ECT图像重建,并利用图像显示程序获得了三维重建图像;最后,对球体及圆柱体模型进行了三维ECT图像重建,获得了较好的重建结果。

Abstract：Simulation research of three-dimensional image reconstruction for electrical capacitance tomography (ECT) was carried out. First, the three-dimensional sensor model of ECT was built using COMSOL software. After that, based on the high accurate solution of finite element method by COMSOL, the sensitivity matrix of ECT was calculated. Secondly, image reconstruction based on linear back-projection (LBP) and Landweber iterative algorithm was realized with MATLAB programming and then the three-dimensional images were obtained by image display program. Finally, image reconstruction was carried out for the sphere and cylinder models and the satisfying results can be obtained.
