Hello friends.
I use pacs servera ORTHANC to send pictures via the Internet to another pacs dicom server using a lua script. Internet speed is 100 Mbit/s, but dicom image transmission occurs at a speed of no more than 1 Mbit/s.
I understand that a dicom image consists of many small files and this prevents fast transfer via the Internet, but has anyone encountered this and is there a solution to this problem?
I tried via OPENVPN, L2TP, Ipsec, but the speed does not change.
Thank you.
Hello,
I assume you are using the DICOM protocol at the moment, perhaps over a VPN or with TLS?
If the destination pacs supports it, you could consider using DICOMweb, where bulk retrieval can be used (WADO-RS), if I am not mistaken.
If not possible, if you are able to deploy an Orthanc instance next to this other PACS, you might want to use the transfers accelerator plugin with a script that automatically stores the images to the PACS on the receiving end.

Hello
I connect 2 pacs servers with a VPN connection. 1 pacs is orthanc, 2 is DCM4CHE.
Do you propose to make the orthank the receiving party and send from it to DCM4CHE?
Hello
Here is your current situation, if I got that right:
Here is a first alternative:
Here is a sample that demonstrates how to transfer from Orthanc to DCM4CHEE in DICOMWeb here
The advantage of DICOMweb is that it supports bulk transfers.
Here is another option that is more complex but perhaps faster:
In that case, if you have control over the “location B” setup, you can add a receiving Orthanc that would immediately transfer to DCM4CHEE (then delete if transfer went well). You could configure both Orthanc to act as peers and rely on the transfer accelerator plugin
HTH
