FakeResampling3D

Fake Nodes scheme for Gibbs-free 3D medical image resampling

This software provides a Fake Nodes resampling scheme for multimodal medical imaging proposed in the preprint

"Reducing the Gibbs effect in multimodal medical imaging by the Fake Nodes Approach". https://arxiv.org/abs/2202.10325

For a sample of its usage, see the main.sh files where the Shepp Logan phantom SL_lq.nii.gz get resampled to the same size of SL_hq.nii.gz both with trilinear interpolation (as provided by ANTs) and with the Fake Nodes approach plus trilinear interpolation.

To verify that Fake Nodes resampling leads to a higher accuracy in assessing the mean value per segment, execute the script main_execution.sh.

Requirements:

• python >= 3.9
• numpy
• scipy
• nibabel >= 3.1
• ANTs https://github.com/ANTsX/ANTs
