What coordinate systems does Slicer use?

See this documentation of Slicer coordinate systems.

How can I use the reformat widget view to resample my images?

You can do something like this in the python console:

red = getNodes('vtkMRMLSliceNode*')['Red']
t = slicer.vtkMRMLLinearTransformNode()
t.SetAndObserveMatrixTransformToParent(red.GetSliceToRAS())
 

Then invert “t” and put my original volume under “t”. Note that it is probably better to copy the matrix rather than observing SliceToRAS directly.
