Slicer Registration Use Case Exampe #14: Intra-subject Brain PET-MRI with MRI orientation adjustment
Objective / Background
Image fusion.
Keywords
PET-MRI, brain, intra-subject, image fusion
Input Data
- reference/fixed : baseline MRI: 0.97 x 0.97 x 3.27 mm , PET: 4.7 x 4.7 x 3.3 mm
- moving: PET: 4.1 x 4.1 x 5 mm
Registration Results
Download

- download example data set (Data only, zip file 135 MB)
- download step-by-step tutorial (PowerPoint 2 MB)
- download registration parameter presets only (zip file with MRML scene files ?? kB)

Discussion: Registration Challenges
- the original DICOM files of the MRI have image orientation data stripped. Hence the volume does not load in correct orientation and needs to be adjusted
- the two series have different voxel sizes
- image content is very different in the PET
Discussion: Key Strategies
- we use the Volumes module to adjust the MRI voxel size based on the info in the DICOM header
- we use the Transforms module to reorient the MRI along the proper axes
- Register Images is used to automatically align the PET with the MRI
