| 摘 要： | 快速而又具在一定精度的图像重建算法是电容层析成像（ＥＣＴ）技术的关键。本文提出一种用多元线性回归法建立ＥＣＴ系统正向模型，用正则化法获得图像重建这一不适宜逆问题稳定解的图像重建新算法。仿真结果表明该方法能快速而较高精度地重建出两相流断层图像。

| Abstract: | Fast reconstruction algorithm with anacceptable accuracy is key to electrical capacitance tomography (ECT). A newreconstruction method is proposed in this paper. The main idea of this method is to modelECT forward problem by using multiple linear regression and obtain a stable solution ofthe image reconstruction problem (an ill-posed inverse problem) by using regularization.Simulation results illustrate that this method is capable of reconstructing the two-phaseflow cross-section fast and rather accurately. |
