Abstract

In this paper, we study speckle reduction technology for 3-D ultrasound images and a 3-D anisotropic diffusion (AD) filter is developed. The 3-D anisotropic diffusion filter works directly in the 3-D image domain and can overcome the limitations of the 2-D anisotropic diffusion filter and the traditional 3-D anisotropic diffusion filter. The proposed algorithm uses normalized gradient to replace gradient in the computation of the diffusion coefficients, which can reduce the speckle effectively while preserving the edges. Experiments have been performed on real 3-D ultrasound images and the experimental results show the effectiveness of the proposed 3D anisotropic diffusion filter.
