[Insight-users] Problem with writing DICOM using KeepOriginalUID

[Martin Kavec]

Thanks a lot for your input, Mathieu,


Here is what I find:

I have 182 files (slices) in the output directories for the both situations, 
KeppOriginalUID On and commeted out. Please note that the number of slices 
(files) omitted by Osirix varies. If I run my code multiple times slices at 
different positions and different number of slices is omitted. So this 
problem is a bit intermittent. For this particular run there were 180 slices 
recognized.

Not OK. The number of unique SOPInstanceUID and MediaStorageSOPInstanceUID is 
correct (182) for the series with KeepOriginalOn commented out, and 181 WITH 
KeepOriginalOn.

After a while I identified the two files having the same SOPInstanceUID and 
MediaStorageSOPInstanceUID, I changed them to a unique ones (checked that) 
and now Osirix reads in 181 slices, that is one more. But still one slice is 
missing.

I found that with respect to the other files/slices in the series with 
KeepOriginalOn commented out, the following tags were left unchanged in one 
or two files: (0002,0013) and (0002, 0012). While this may not affect my 
situation, it is strange that these tags were left behind.

Is there anything more I could test?

Thanks a lot,

Martin
