The Slicer Registration Case Library
Welcome to the 3DSlicer Registration Case Library. This page is under continuous development as we add and refine case examples of image registration within 3DSlicer. The goal is for you to find in here a case similar to yours that will address the issues of your particular image registration problem and give you a promising start. Successful registration strategies vary greatly for different image contrast and content. You will find 3 sets of content with each case: 1) a step-by-step tutorial that will show you how to use 3DSlicer to register images of this type, 2) the example dataset used in the tutorial so you can try for yourself, along with the solution transform so you can compare, and 3) a custom Registration Presets file that contains the optimized registration parameters that you can load directly into slicer.
BRAIN
The Same Subject Brain MRI collection contains cases of co-registering different structuralMRI protocols of the same subject, e.g. aligning a T1w and a PDw image. DTI and fMRI cases are handled separately, see columns to the right.
The Same Subject DTI collection contains cases of registering a DTI dataset with an anatomical reference, such as a high-resolution MRI.
The Same Subject fMRI collection contains cases of registering a fMRI dataset with an anatomical reference, such as a high-resolution MRI.
The Same Subject PET/CT collection contains cases of registering a PET or CT dataset with an MRI or CT.
The Different Subject Brain MRI collection contains cases of co-registering different structuralMRI protocols of the same subject, e.g. aligning a T1w and a PDw image. DTI and fMRI cases are handled separately, see columns to the right.
The Different Subject PET/CT collection contains cases of registering a DTI dataset with an anatomical reference, such as a high-resolution MRI.
The Different Subject Brain Atlas collection contains cases of registering an atlas to a single subject or building atlases from a collection of subjects.
OTHER
The Abdominal collection contains cases of registering different datasets of the same subject.
The Musculoskeletal collection contains cases of aligning multiple datasets into a common reference space.
The Whole Body PET/CT collection contains cases of registering different modalities of whole body imaging.
The Animal MRI/CT collection contains cases of aligning animal datasets.
How to get started
- 1. browse/search the library below for a case similar to yours. The library is organized by organ (brain vs. non-brain), modality (MR, CT, PET), intra- vs. inter-subject). Each case also has a list of keywords, so you may try a direct search for a case matching yours.
- 2. If you find a good match, continue with 3. below. If you cannot find a good match, consider our Call for Datasets & Registration Service.
- 3. from the case description page, follow the links to download the data, preset file and tutorials.
- 4. run the tutorial on your machine with your installation of slicer
- 5. load the preset file and try those settings on your own data
- 5. if you do not get a satisfactory registration results with the presets, have a look at the Registration Challenges and Key Strategies section on the download page of your case. You will find recommendations there on how to venture forth. Try the recommended adjustments.
- 6. if still unsuccessful you may have a case of interest to the library. Consider adding your case to the library for a free registration. Also consider posting a message to the slicer user group.
Source & Format
Data is collected from a variety of sources. Most we hope to originate from user contributions. 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 reformatted as NiFTI files. Cases under construction may be listed, and when complete a download link is added.
- Call for Datasets
- All image data is anonymized, i.e. there is no identifying or patient specific information in any of the posted data. We do not keep identifiers, so we cannot retrace.
- 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.
- If desired, links & contact info to the contributor lab are provided.
- Links here also from the NA-MIC resource page.To be updated when moving.
