Hi Matt,

I have never worked with nifti images but I know there are problems handling 
rotated geometries in case of 2D images. If a 2D image is rotated in the 3D 
space the information about the 3D rotation is currently lost when the image is 
loaded. As a solution we are planning to handle 2D images like 3D images 
consisting of one slice. This will be done during the whole geometry 
refactoring process (bug 8910) but we are currently in the 
planning/specification phase of the refactoring since these fixes will bring 
bigger changes in MITK.

Regards
Andreas
