Problem with inserting private tag

[new2009]

I am using dcmodify.exe (Windows) version 3.6.0 and trying to insert private tag (1041,1010) with value "AR".

From what I read in the dcmodify manual, I need to add this (reserve) in the "data dictionary".

But, I do not know how to do this for the Windows version of DCMTk.

Is that even possible? How?

Right now, I can force the insertion using --no-reserv-check, but then I got "UN" VR and the inserted value was set as 0a\00.

Thanks.

After I read the instruction to create additional data dictionary from:
http://support.dcmtk.org/docs/file_datadict.html

I created one in C:\TEMP\data.dic

Containing this single line:
(1041,"PHILIPS",1010) SH Unknown 1

All fields are separated by TAB characters.

The data dictionary was loaded properly, but the error is still there:

Code: Select all

C:\Temp>set DCMDICTPATH=C:\TEMP\data.dic

C:\Temp>dcmodify -i "(1041,1010)="AR"" IM_0001.dcm
I: DcmDataDictionary: Loading file: C:\TEMP\data.dic
E: modifying tag in file IM_0001.dcm: Invalid path: No private reservation found for tag: (1041,1010)
E: There was 1 error

What is wrong here?

I think the error message is quite obvious: "No private reservation found for tag: (1041,1010)"

That means you also have to add the private creator element (1041,0010) with a value of "PHILIPS".
If you don't understand this, please read the relevant sections of part 5 of the DICOM standard!

How do you add that in the data dictionary?

Is it not possible?

No, the private creator element should be added to the DICOM dataset, of course

You said here: viewtopic.php?f=1&t=3415&p=13623&hilit=private#p13623

"Btw, you could also add your private tags to a loadable data dictionary (see "private.dic")."

And that's what I am trying to do, with no success

Ah, OK! Understand.

I did this:

Code: Select all

C:\Temp>dcmodify -i "(1041,0010)=PHILIPS" IM_0001.dcm
I: DcmDataDictionary: Loading file: C:\TEMP\data.dic

C:\Temp>dcmodify -i "(1041,1010)=AR" IM_0001.dcm
I: DcmDataDictionary: Loading file: C:\TEMP\data.dic

And it works!

Great

Btw, you can insert multiple data elements with a single call using option -i multiple times.
