[Insight-users] DICOM tag to sort a serie

[Alfredo Gourbish]

Hi all,

I have a problem with sorting DICOM images using GDCM. In fact, I use some tags to differentiate the volumes (4D volumes) in the serie. My problem is that the tag corresponding to Temporal Position Identifier (0020|0100) has values like that : "1", "2", "3", ..., "10", "11", "12", ..., "20", ..., "33", ...
So finally, the volumes will be sorted like this : 1, 10, 11, 12, 13, ..., 2, 20, 21, ..., 4, 5, 6, 7, 8, 9 because it's an alphabetical order.
In fact, the Temporal Position Identifier may have number like that : "01", "02", ... and the problem would be solved.

I hope you understand my problem since I have not yet find a solution. So if anyone has an idea...

Thank's !

Gourbish
