Source

Data is collected from a variety of sources. Because we want to focus on the registration problem and not be distracted by image format or other data management issues, the datasets listed here are copied and reformatted. As the data becomes available a download link is added.

• Options for the download location is a direct link to a download page from the main 3Dslicer user page or XNAT Central. The former seems preferable, since the general XNAT GUI appears too complex for a simple 1-case download. We expect most users to download only 1 or 2 files closest to their particular use case, not entire study sets. Such download should be acessible with 1-2 clicks, as with other slicer resources.
• Disk usage: Likely these example sets will grow no larger than 10GB. Estimating 50-80MB per case would allow 60-100 cases within a 5GB space.
• Since we post reformatted and preprocessed data, where possible the link to the original source is provided.
• Links here also from the NA-MIC resource page.To be updated when moving.

Categories & Formatting

• Ideally we seek 2 sets for each use case to define a range of settings, i.e. one case that is average and works reasonably well, and one case that is more challenging. Both cases together then define a range. The two cases would be posted together, provided the difficult case can be solved with different settings and does not require a different approach. The latter case would then be better listed in a Troubleshooting category.
• The main categories will follow along the hierarchies outlined [here].
• We seek to have all datasets in a single-volume file format, most likely .nii or .nrrd
• Once formatting, anonymization and description are complete, listing here will be replaced with a download link. Temporarily listed are links to source databases, where avail.

Case Inventory Brain

• Intra-subject T1-T2-DTI
  • DTI baseline to T1 inter-subject with clipped FOV
  • DTI affine & non-rigid alignment
• Intra-subject PD,T2, T1Gd (MS)
  • Scan-rescan intra-subject. No change.
  • UNC Midas Database of healthy volunteers
  • fMRI: inter-subject structural scan to MNI atlas target

Case Inventory Non-Brain

• PET-CT whole body, 2 timepoints each -- see here
• breast Cancer MRI: pre- and post-treatment
• breast Cancer - original data, two time points after some registration and processing
• prostate image database (intra- and inter-subject registration use cases) http://prostatemrimagedatabase.com/index.html
• knee registration for Simbios project -- http://slicer.spl.harvard.edu/slicerWiki/index.php/Stanford_Simbios_group
• liver tumor ablation: pre-procedural MRI to intra-procedural CT --> Dr. Stuart Silverman's IGT group: manuscript
• kidney tumor ablation: pre-procedural MRI to intra-procedural CT --> Dr. Stuart Silverman's IGT group
• liver CT, intra-subject, contrast enhanced manuscript
• temporal bone (ear) intra-subject CT to MRI of the collab with Soenke in 2005
• tibia CT, Model-based surface registration

Case Inventory Non-human

• Vervet Atlas

Self-validation Sets

These are datasets with artificial misalignment, i.e. the perfect alignment is known.

• Dual Echo PD/T2 intra subject different contrast self validation
• Isotropic Brain SPGR T1 with single axis rotation

First 10 cases (not in sequential order)

• Brain intra-subject, same contrast T1, change detection follow-up: tumor growth
• Brain MRI, intra-subject, same contrast PD&T2, change detection follow-up: new MS lesions
• Brain MRI, intra-subject, different contrast, co-register all series of the same exam: T1 SPGR, FLAIR, T2
• Brain MRI, intra-subject, DTI to reference, apply Xform to 25-direction DTI tensor
• Brain MRI, intra-subject, example with clipped FOV, example of masking required
• Brain MRI, inter-subject, co-register T1 SPGR to atlas dataset (ICBM). Resample a label map.
• Liver intra-subject, pre-procedural MRI to intra-procedural CT
• Prostate MRI, intra-subject
• Knee inter-subject registration to initialize segmentation
• PET to CT Whole Body single timepoint
• Breast Cancer: feasible with affine focus?
