Dear NifTI experts,
We are trying to work out the slice acquisition order of Dicom images
(coming from a GE scanner).
Our fMRI analysis software reads the slice aquisition order from the
NifTI field slice_code. This can be
0 unknown
1 sequential increasing ( 0, 1, 2, ... )
2 sequential decreasing ( N, N-1, N-2, ... )
3 alternating increasing ( 0, 2, 4, ..., 1, 3, 5, ... )
4 alternating decreasing ( N, N-2, N-4, ... N-1, N-3, N-5 )
and the program uses the default setting (alternating increasing) when
it reads 0. It would be ideal to sort this question right during the
conversion Dicom -> NifTI, but none of the Dicom fields seem to deal
with this issue.
Is there any convention that can be used to set the slice order
appropriately?
Many thanks
Alle Meije Wink
