An Adaptive Iteration Algorithm Used for Speckle Reduction Diffusion in Ultrasound Imaging

In this paper, we propose an adaptive iteration algorithm used for speckle reduction diffusion. In order to reduce the iteration times and improve the result image, we propose to use relative peak signal to noise ratio as a criterion of step changing during iteration. To evaluate the performance of the proposed algorithm, we use synthetically introduced speckle images for speckle suppression. The simulation results show that our method not only preserve image details effectively while filtering, but also reduce the iteration times.
