How to use DCMTK-getscu to retrieve DICOM instances from Orthanc

General
1

In Understanding DICOM with Orthanc — Orthanc Book documentation, it has an example:

  1. Add in orthanc.json, add “getscu” as:
    {
    “DicomModalities” : {
    “getscu” : [ “GETSCU”, “localhost”, 2000 ]
    }
    }
  2. getscu -v localhost 4242 -aec ORTHANC -k “0008,0052=STUDY” -k “0020,000d=<study.uid>”

However, it failed with error:
DICOM authorization rejected for AET ORTHANC on IP 127.0.0.1: This AET is not listed in configuration option “DicomModalities”

Tried and failed again:
getscu -v localhost 2000 -aet GETSCU -k “0008,0052=STUDY” -k “0020,000d=<study.uid>”

Please help. Thanks in advance!!

Hi,

Your config looks ok.
Here’s the command I’ve been using for testing:

getscu -S -k "QueryRetrieveLevel=Study" -k "StudyInstanceUID=1.2.3" localhost 4242

and the output in verbose mode:

Thanks for help!

Unsuccessful:

Thanks! [getscu -S -k “QueryRetrieveLevel=Study” -k “StudyInstanceUID=1.2.3” localhost 4242] works by adding into Orthanc.json:
{
“DicomModalities” : {
“getscu” : [ “GETSCU”, “localhost”, 2000 ]
}
}
