can't modify OtherPatientIDs ?

Hi there,

Small question, in the main dicom tag at patient level, in some case the OtherPatientIDs is available (most often existing tag but empty “”).

I tried to modify this tag with the /modify API, if I include the “OtherPatientIDs” in Replace or Remove payload of modify API, i get http 500 with this answer

body: ‘{\n’ +
‘\t"HttpError" : “Internal Server Error”,\n’ +
‘\t"HttpStatus" : 500,\n’ +
‘\t"Message" : “Unknown DICOM tag”,\n’ +
‘\t"Method" : “POST”,\n’ +
‘\t"OrthancError" : “Unknown DICOM tag”,\n’ +
‘\t"OrthancStatus" : 27,\n’ +
‘\t"Uri" : “/patients/…/modify”\n’ +
‘}\n’
}

Is it normal ? is this tag not editable or is it a bug ?

Best regards,

Salim

Hello Salim,

The “OtherPatientIDs” tag is now retired in the DICOM standard. You should use the “RETIRED_OtherPatientIDs” symbolic name or, better, the hexadecimal value “0010,1000” to access the tag across different versions of DCMTK.

New applications should use “OtherPatientIDsSequenceAttribute” (0010,1002) in place of “OtherPatientIDs”. For instance:

$ curl http://localhost:8042/studies/66c8e41e-ac3a9029-0b85e42a-8195ee0a-92c2e62e/modify -d ‘{“Replace”:{“OtherPatientIDsSequence”:[{“PatientID”:“HELLO”}]}}’

HTH,

Thanks Sebastien for your answer,

I will simple filter out this item,

being retired do you plan to switch the “OrtherPatientIDs” to “OtherPatientIDsSequenceAttribute” in MainDicomTags in patient level orthanc API response ? or let this way for non breaking existing install ?

Best regards,

Salim

Hello,

There is no plan to replace “OtherPatientIDs” in the Orthanc REST API, as this would indeed break downward compatibility, which is something we absolutely want to avoid.
