Hi, I'm comparing 2 ways of getting/transforming dicom files, and there
seem to be some differences in the header of the two final 4D images. I
don't know the meaning of some of these fields though, could I get a
little input please?
The two 4D files differ mainly in the following fields
PIXDIM[4-->7] Being 1,0,0,0 in one case and 2,1,1,1 in the other. (there
is also a little truncation in the X,Y,Z pixdim e.g. 3.00000 v 3.0000014305)
qform_name Unknown in one case vs Scanner anat
qform_code 0 vs 1
(the two sform fields are identical though)
qto_xyz[1-->3] are substantially different
qform_'x,y,z'orient are all different (although they appear identical in
FSLVIEW)
one of the two loses the "description" field information.
The basic problem is that, not understanding all of these fields I'm not
sure if this is a non-problem or if it is!
thoughts?
