Lossy Compression(New SOP Instance UID Created)

[Akshaybar Singh]

Dear All,

I am compression the DICOM file using DCMTK 3.6.0 withh Lossy Compression(EXS_JPEGProcess10_12TransferSyntax).

I have register the codec before going to compress the file. Lossy compression has been done by DCMTK but it creates NEW SOP INSTANCE UID for the same image update the tag (0008,0018) with new SOPInstanceUID.

My requirement is to not update SOPInstanceUID with new sopUID, it shall be with original SOP Instance UID.

Kindly help to do the same. How can stop the creation of new SOP Instance UID for Lossy Compression?



Thanks & Regards
Akshay

Hi,

dcmcjpeg has an option to disable creation of a new SOP Instance UID (--uid-never). You can look into dcmcjpeg.cc how the parameter is handed over the compression codec if you want to do the same in your source code instead of using the tool.
