摘要研究了灵敏度矩阵更新的Landweber迭代图像重建算法,以期提高重建图像精度。灵敏度矩阵更新时的初始图像由Landweber迭代法获得,对不同迭代次数的灵敏度矩阵更新间隔进行了比较,并且对灵敏度矩阵的更新次数进行了分析,仿真及实验结果表明,该方法能有效提高图像重建精度。

Abstract：Landweber iterative algorithm with updated sensitivity matrix is studied to improve the quality of reconstructed images. The initial image for sensitivity matrix update was obtained by Landweber iterative algorithm, and the results of different sensitivity matrix update intervals are compared. The times of sensitivity matrix updating are also analyzed. Experimental and simulation results showed that reconstructed images with higher accuracy can be obtained.

Key words： metrology electrical resistance tomography image reconstruction algorithm landweber iteration multiphase flow measurement
