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.
