[Insight-users] DICOM series private tag

[Alberto Bert]

Hi all, thanks Mathieu,

I have actually activated the private tags, atleast I think so. Below
you'll find my code.  

If I use "0054|1300" as series restriction, then the slices are grouped
correctly by time frame (series), but the frames are not sorted correctly,
namely the one corresponding to time=20000ms is after the one with
time=100000ms, due to the string sorting of the GDCMSeriesFileNames, I
bileave. If I use "0009|10d8" instead, all the images gets in the same
series. If I try to print out (using a variant of
DicomImageReadPrintTags.cxx) the "0009|10d8" value, I get:

Frame number (0009|10d8)  is: AQAAAA==

While if I try to see its value with DCMTK (dcmdump) then I get the right
values written as:

(0009,10d8) ?? 01\00\00\00

So, that's why I though it could be a format issue.

I've found about this dicom tag in an email to this list, by Kris, but he
hasn't explained how to use it or print it.

Sorry for not have being clear in the previous email, and thanks again 
for your time.
