How to modify existing tags in the dictionary?

I want to change the nicknames of some tags in the dictionary of DICOM tags from DICOM to DICONDE. At the orthanc.json configuration file new tags can be registered, but if I try to modify existing tags, nothing happens.

e.g.:
“Dictionary” : {
“0010,0010” : [ “PN”, “ComponentName”, 1, 1 ]
}

How can I modify existing tags in the dictionary?

And how can I change the text at the Orthanc web-explorer from “Patient” to “Component”?

Hello,

Back to this old thread, Orthanc 1.9.4 (to be released soon) will support using the DICONDE dictionary thanks to the new “ExternalDictionaries” configuration option:
https://hg.orthanc-server.com/orthanc/file/dd6274412ff4/OrthancServer/Resources/Configuration.json#l627

Here is the corresponding full changeset:
https://hg.orthanc-server.com/orthanc/rev/dd6274412ff4

You can find a screenshot of Orthanc Explorer displaying a DICONDE file attached to this message. As highlighted in red, Orthanc does use the DICONDE tags (such as “ComponentName” or “ComponentManufacturerDate”).

However, as Orthanc Explorer is primarily a Web interface targeted at developers, the wording “Patient” is still used even if displaying a DICONDE “Component”. The rationale can be found in the Orthanc Book:

Kind Regards,

Hello,

I have configured the orthanc.json file is configured as

grafik
grafik562×207 4.68 KB

However, the Orthanc Explorer is still showing PatientID and PatientName instead of ComponentIDNumber and ComponentName after restarting the service.

What can be the reason that it is reading another dicom.dic and than the path specified in the json configuration file?
