Adding dicom tags to viewport about viewers HOT 3 CLOSED

Hi Martin,

It looks like studyComments has not been added to the Cornerstone metadata provider. Check here:

https://github.com/OHIF/Viewers/blob/b2c5b587bc6ec68164466a989412876aee053400/Packages/viewerbase/lib/metaDataProvider.js#L40

Called from here:

Hope that helps!

Hi Erik,

Thanks for the tip, however I am still unable to display this dicom tag in the viewport. Instead of adding it to studyMetaData, I have added it to instanceMetaData in metadataProvider:
metaData.instance = { wadouri: instanceMetaData.wadouri, imageType: instanceMetaData.imageType, photometricInterpretation: instanceMetaData.photometricInterpretation, sopInstanceUid: instanceMetaData.sopInstanceUid, sopClassUid: instanceMetaData.sopClassUid, instanceNumber: instanceMetaData.instanceNumber, laterality: instanceMetaData.laterality, viewPosition: instanceMetaData.viewPosition, sliceThickness: instanceMetaData.sliceThickness, studyComments: instanceMetaData.studyComments, index: imageIndex };
I added this line to Instance level in QidoRs.cpp in Orthanc:
result.push_back(gdcm::Tag(0x0032, 0x4000)); // Study Comments

I also added this line to instances.js in qido:
studyComments: DICOMWeb.getString(instance['00324000'])

I added this line in ViewportOverlay.html:
<div>{{studyComments}}</div>

And finally this line to ViewportOverlay.js:
studyComments: function() { return getInstance.call(this, 'studyComments'); },

I have double checked whether or not the DICOM tag is correct (and it is). The tag is filled as a string, which I can confirm when looking at the initialisation of DICOM tags in the instance level of orthanc.

UPDATE: I can add dicom tag 0008,0070. It is displayed wonderfully in the upper left corner. Once I replace this tag with 0032,4000 (the desired tag), it stays blank. I suspect it is because this is not a regular DICOM tag, but added by the specific software manufacturer.

I guess there should be a translation file in which all standard dicom tags are noted. I remember a file called dataDictionary.json. Any idea what the exact location of this file is?

Is there a max on the length of a DICOM string? Because the dicom tag contains 123 characters.

I shall keep you informed.
