Import DICOM files from a cloud PACS

Hi, how can I import all the studies from a cloud PACS to the Orthanc that I have installed on localhost?

All depends on what is your “cloud PACS”. If this is Orthanc, check out the “Replicate.py” script:

If this is a DICOMweb server, you can manually download the content using the DICOMweb plugin (and possibly automate using its REST API):

Finally, if this is proprietary cloud server, contact the commercial support of your supplier:
