SLIMMER
The Slice MRI Motion Estimation and Reconstruction (SLIMMER) tool is intended to allow the formation of a single
3D high resolution image from multiple sets of lower resolution multi-slice
MRI data, where regional tissue motion can occur between the acquisition of slices.
The input data is a set of raw DICOM format multi-slice data. The final output is a single volume
image in GIPL or NIFTI format. The plugin tool for rview provides a graphical user interface to
load data, automatically initialize the stack alignment from scanner coordinates, select the region of interest
and then to inspect the result of regional between-slice motion estimation, bias inconsistency correction
and volume reconstruction algorithms.
