提出了一种新的电容断层扫描（ECT）迭代重建技术。该方法应用迭代软阈值来惩罚 ECT 图像的总变化。与 ART、SIRT 和 Landweber 迭代等传统迭代重建技术不同，该方法允许模拟 ECT 图像的不同区域之间出现急剧变化。该技术通过具有不同气体和固体区域的模型的实验结果得到了证明。因此，该技术适用于多相系统的成像。
A new iterative reconstruction technique for electrical capacitance tomography (ECT) is presented. This method applies iterative soft thresholding to penalize the total variation of the ECT image. This method is shown to allow for sharp changes between different regions of simulated ECT images, unlike conventional iterative reconstruction techniques such as ART, SIRT and the Landweber iteration. The technique is demonstrated on experimental results for a phantom with distinct regions of gas and solid. The technique is therefore appropriate for the imaging of multiphase systems.
