Connectivity with unregistered modalities

General

My orthanc configuration file has the following codes:

“DicomAlwaysAllowEcho”: true,
“DicomAlwaysAllowFind”: true,
“DicomAlwaysAllowStore”: true,
“DicomAlwaysAllowGet”: true,

Is it still mandatory to add the Dicom Modalities in the orthanc json file or in database? As per my understanding, the above codes allow communication even if the modalities are not registered. Kindly confirm.

Your understanding is correct.

Thank you. But, that’s where I’m getting an issue. I’m trying a ping operation from a Philips Ingenia MRI modality, which isn’t added in the Dicom Modalities configuration. But the other parameters mentioned above, are set. Yet, the ECHO operation from the modality isn’t working. Please help me out.

Hi,

Then it’s a network connectivity issue or a firewall blocking the transfer but very likely not Orthanc rejecting the ECHO.

You may use tcpdump to log all incoming traffic on the machine running Orthanc if you want to validate it.

HTH,

Alain
