Slicer Registration Library Exampe #26: Fusion of WM parcellation atlas with anatomic brain atlas
Objective / Background
This is an example of inter-subject registration. The structures of interest are WM parcellations from the JHU-MNI atlas (see acknowledgments).
Keywords
MRI, brain, head, inter-subject, atlas to atlas, WM parcellation
Input Data
moving: b0 image of JHU_MNI white matter atlas. Called A2_gray
tag: WM parcellation labelmap A2_label
Methods
Registration Results
Download
- download SPL atlas (MRI T1+T2, labelmaps , colormap file with label names), zip file 126 MB)
- download JHU-MNI Mori / "Eve" Atlas (MRI T1+T2, 3 labelmaps with WM parcellation, 3 Slicer LUT text files with label names + Colors), zip file 28 MB)
- download Label & Color LUT (diffferent formats of LUT text files with label names, colors, comments ), zip file 50 kB)
- Mori Atlas page on Slicer Wiki
- LUT converter website
- Link to User Guide: How to Load/Save Registration Parameter Presets
Discussion: Registration Challenges
- the two atlases represent different anatomies and hence some residual misalignment is inevitable
- the two labelmaps have different resolutions and different smoothness of structure outlines. Some need filtering to remove spurious surface details that would distract the registration algorithm
Discussion: Key Strategies

"We are pleased to make our white matter atlas available. The JHU-MNI-ss atlas, which is often called "Eve Atlas", is based on a single-subject data as described in Oishi et al, 2009. There are co-registered T1 (MPRAGE), T2, and DTI images as well as white matter parcellation map (WMPM). Once the image of interest is normalized to this atlas coordinate, the WMPM (which also includes gray matter structures) can be superimposed for anatomical definition (e.g. which structure is affected by a lesion or where exactly is the fMRI activation site) or automated segmentation. All images have 181x217x181 / 1x1x1 mm dimensions."
