We propose a new pipeline (DESIGNER) for diffusion
image processing that includes Marchenko Pastur denoising and Gibbs artifact removal,
and thereby improves the precision and accuracy of the diffusion tensor and
kurtosis tensor parameter estimation. In particular, our results show no notorious
black voxels on kurtosis maps, while the original resolution is maintained in
contrast to state-of-the-art processing methods that apply smoothing.
