Improvement of 3D visualization of the brain using anisotropic diffusion smoothing of MR data.
This paper deals with an iterative 3D smoothing of MR images acquired by fast 3D Flash sequences. The method explored, which is aimed at improving 3D visualization quality, uses the physical concept of anisotropic diffusion. A novel iteration stopping criterion is proposed and tested. The results of computer experiments with 3D smoothing, segmentation, and visualization using actual MR brain data are presented and discussed.
