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
Original unregistered CT images.
Download
- download full tutorial set (Data+intermediate results+presets+tutorial, zip file ?? MB)
- 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)
Link to User Guide: How to Load/Save Registration Parameter Presets
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
