Hello,
Will Orthanc merge two studies if they have same patient-id and accession number ? What about if they have same patient-id and study-id?

You might consider that studies will be “merged” if they share the same Orthanc id. Check how Orthanc ids are computed to predict how they will be “merged” (http://book.orthanc-server.com/faq/orthanc-ids.html).

As explained in the FAQ pointed out by Alain, accession number is not taken into account by Orthanc to group studies. The decision rule is the following:

  • Different patient IDs => studies not grouped
  • Same patient IDs, different StudyInstanceUIDs => studies not grouped
  • Same patient IDs, same StudyInstanceUIDs => studies grouped

Thank you for clearing things up.
