Issue with C-FIND on 0010,21C0 (PregnancyStatus)

General

I’m writing a modality worklist plugin and everything is working great except the PregnancyStatus attribute. Which I wouldn’t bother with except my ultrasound machine sends this over as null when it’s requesting a modality worklist which alone blocks my mwl plugin from functioning. I have no way to prevent it from doing so. I assume this issue extends beyond MWL and impacts all C-FIND omitting (requesting) PregnancyStatus.

For example, if I run this query:

findscu -v -W -k 0008,0052=WORKLIST -k 0008,0060=US -k 0010,0010 -k 0010,21C0 127.0.0.1 4242

it will fail for reason:

E0919 18:52:05.167445 DICOM-2 OrthancException.cpp:62] Bad file format: While creating a DICOM instance, tag (0010,21c0) has out-of-range value: ""

However, no other -k attributes that I omit will cause this same issue and PregnancyStatus is coded properly in my output. For example, if I run this query (omitting the return of PregnancyStatus) it will succeed:

findscu -v -W \
  -k 0008,0052=WORKLIST \
  -k 0008,0060=US \
  -k 0008,0050 \

Nevermind, you can delete this topic. I found the solution for PregnancyStatus in the ModalityWorklist example in the Plugins/Samples folder.

That one is special, an enumerated value: Pregnancy Status Attribute – DICOM Standard Browser
