MONAILabel Plugin for OHIF Viewer

Release mode

pip install monailabel will install the OHIF that is pre-built with MONAI Label.
OHIF will be accessible at http://127.0.0.1:8000/ohif/ when you start monailabel server connecting to local/remote dicom-web storage.

Development setup

• Build the OHIF plugin for development:

  (cd plugins/ohif && ./build.sh)

• Run App with Orthanc (DICOMWeb):

  ./monailabel/monailabel start_server -a samples/segmentation_spleen -s http://127.0.0.1:8042/dicom-web

• Access OHIF: http://127.0.0.1:8000/ohif/

# If you want to avoid building OHIF package for every code changes, 
# you can run OHIF Viewer directly in checked-out git submodule
cd plugins/ohif/Viewers

yarn run dev:orthanc

# in this case ohif will run at http://127.0.0.1:3000/
xdg-open http://127.0.0.1:3000/

Converting NIFTI images to DICOM

plastimatch convert --patient-id patient1 --input image.nii.gz --output-dicom test 

Converting NIFTI Annotations to DICOM-SEG

If you'd like to upload image annotations to the DICOMWeb server (i.e. Orthanc), you should use DICOM-SEG. For that you could use itk tools such as itkimage2segimage (https://qiicr.gitbook.io/dcmqi-guide/opening/cmd_tools/seg/itkimage2segimage).

Uploading DICOM to Orthanc

Use Orthanc Browser

Use orthanc browser located at http://127.0.0.1:8042/app/explorer.html#upload to upload the files.

Using STORE SCP/SCU

Enable AET

sudo vim /etc/orthanc/orthanc.json

"DicomModalities" : {
/**
 * Uncommenting the following line would enable Orthanc to
 * connect to an instance of the "storescp" open-source DICOM
 * store (shipped in the DCMTK distribution) started by the
