Something similar happened to me with a CT DICOM series, and 
after some headaches I found out that the "through plane 
distance" was correctly set by ITK. Check the Slice Location 
tag of the DICOM files. The difference between the location of
two consecutive slices should be your final distance between 
planes---at least this is what happens with my files.

Hope it helps,
