[NOOR AHMED]

Hi, 

We have two source at machine cosole. if user send one copy directly to orthanc Dicom router and one copy of same study send to pacsone. then pacsone route same study to orthanc Dicom Router, 

my query is that , can orthanc accept  only single entry from different source and route single entry to destination or same duplicated copies can be routed to RRO or Comiere Orthanc twice?

Please need suggestion and help.

During the reception of studies, Orthanc works at the "DICOM instance" level (the study these instances belong to is not taken into consideration).

The notion of patient/study/series is only considered for the "on stable" events:

If you route at the instance level, and if each DICOM instance is automatically removed from Orthanc after having been routed, receiving a second copy of the instance will route it again. If your routing script doesn't remove the original instance, the behavior of Orthanc depends on the "OverwriteInstances" configuration option:

https://hg.orthanc-server.com/orthanc/file/Orthanc-1.9.3/OrthancServer/Resources/Configuration.json

  // Specifies how Orthanc reacts when it receives a DICOM instance
  // whose SOPInstanceUID is already stored. If set to "true", the new
  // instance replaces the old one. If set to "false", the new
  // instance is discarded and the old one is kept. Up to Orthanc
  // 1.4.1, the implicit behavior corresponded to "false".
  "OverwriteInstances" : false,
