custom url protocol

I have a question:

Can Orthanc be launched from a web browser using a custom url protocol like slicer://, weasis:// or horos:// ?

I am trying to launch orthanc and retrieve a study using wado-uri like I do with osirix: osirix://?methodName=downloadURL&URL=‘http://www.myserver.com/dicomfile.dcm’

Hi,

No, custom url protocol is not supported in Orthanc right now.

Best regards,

Orthanc is a Web server with a Web interface and a REST API, so there is no need for a URL scheme like “slicer://” or “weasis://”. You just have to use the standard HTTP/HTTPS protocol, like in: “http://localhost:8042/”.

If you want to download a ZIP archive containing a study, you could for instance use:

$ curl https://demo.orthanc-server.com/studies/6c65289b-db2fcb71-7eaf73f4-8e12470c-a4d6d7cf/archive > /tmp/a.zip

The reference of the REST API can be found at the following locations:

Thank you for your reply.

I think I didn’t explain my use case well enough:

What I want to do is use a link in my browser to control a local instance of orthanc to retrieve a study from a remote server (or simply to download a dicom file from an URL). In other words I want to download DICOM files by URL into my local orthanc instance from any remote server.

Is that possible using the Othanc API?

Yes, it’s possible, but depending on the api of your remote server. One case possible in Orthanc ecosystem is the Query/ Retrieve function. When you click the Query/Retrieve button, it means you call an api from Orthanc to perform C-Get/ C-Move dicom from remote server to your Orthanc. Another case is Transfer Accelerator Plugin (https://book.orthanc-server.com/plugins/transfers.html), if you are using Pull mode, you call an api from your local Orthanc to a remote Orthanc to download the instance/ series/ study. Besides those case, you can create a plugin (by C++ or Python) to customize api calling to your remote Server and then upload them to your local server.
