Sample Applications |
| LinCoregL3 |
- Rigid image alignment using up to 12 parameters as selected.
- Mutual Information, Cross-Correlation or Least Squares matching criterion.
|
- Longitudinal study image alignment, e.g. preliminary to
BBSI.
- Multi-modality image alignment (e.g. flairs to T1 for same subject).
- Cross-sectional study image alignment to template, prior to non-linear warping.
|
| SplineWarp |
- Cubic B-Spline warping using multiresolution and multigrid hierarchy.
- High dimensional warp involving up to 750K parameters.
- Automatic intensity-based matching using Cross-Correlation.
|
- Cross-sectional studies in which statistics are generated from the warps of all subjects onto group template.
- Group differences using Jacobian images (also see
C3Jacobian).
- Voxel-based regression images showing group correlations at each voxel with other factors like cognitive scores.
|
| SliceAlign |
- Correction of misaligned slices in MRI images
|
- In images containing excessive head movement, readjust each slice to better match neighboring slices.
- Minimize misalignment artifacts by estimating translation and rotation corrections slice by slice.
- Commonly applied to images with thick (> 3mm) slice size, e.g. DSE and FLAIR
|
| TPWarp |
- Thin-Plate spline warping of images to match landmarks.
|
- Biometric studies of group differences based upon landmark positions.
- Landmark-based enhancement of automatic intensity-based cubic-spline warps.
