Auto Routing

Hi!

I’m testing the script HighPerformanceAutoRouting.py

Two observations:

  1. Filter AE Title: In DicomModalities, i messed up the AE Title and yet sent the images to remote modality. Only the host and port to send the images. Variable AE Title is not necessary? Note: Orthanc – to —> Orthanc.

  2. Is possible to adapt the script to use the “OrthancPeers” section?

Very thanks!

Hello,

I’m testing the script HighPerformBy default, Orthanc does not filter incoming images with the AE Title of the remote modality. You can enable this filtering by setting the option “DicomCheckCalledAet” to “true” in the configuration file:anceAutoRouting.py

  1. Filter AE Title: In DicomModalities, i messed up the AE Title and yet sent the images to remote modality. Only the host and port to send the images. Variable AE Title is not necessary? Note: Orthanc – to —> Orthanc.

By default, Orthanc does not filter incoming images with the AE Title of the remote modality. You can enable this filtering by setting the option “DicomCheckCalledAet” to “true” in the configuration file:http://orthanc.googlecode.com/hg-history/Orthanc-0.6.2/Resources/Configuration.json

Sure, you just have to replace “/modalities/” by “/peers/” at the following line:
https://code.google.com/p/orthanc/source/browse/Resources/Samples/Python/HighPerformanceAutoRouting.py#96

By making this substitution, the images will be sent through HTTP (i.e. through the REST API) rather than through the DICOM protocol.

Surprising features of Orthanc.
Thanks Sébastien.

Hi!

I tried but did not work.

I’m using the latest version with Python 2.7, both Windows and Linux.

First attempt, prompts to install the module httplib2.

My Configuration.json

“OrthancPeers” : {

“pacsbr” : [ “https://my.ip”, “user”, “pass” ]
},

My HighPerformanceAutoRouting.py

lines: 5-6
URL = ‘http://localhost:8042’

TARGET = ‘pacsbr’

line: 96
RestToolbox.DoPost(‘%s/peers/pacsbr/store’ % URL, instances)

Result in Linux:

401 is for The request failed with HTTP status 401: Unauthorized

I Forgot To Tell, works great with the HTTP GUI.

Thanks,

Vinicius,

It looks as if you have setup a password for the REST API of the “sender Orthanc”, but the autorouting script (that continuously monitors the incoming instances in Orthanc) is not aware of this password. You need to write a line such as the following one at the beginning of your Python script:

RestToolbox.SetCredentials(“username”, “password”)

If adding such a line does not help, please could you send me your full configuration files (for the “sender Orthanc” as well as for the “receiver Orthanc”), as well as your full autorouting script (of course, hiding your true passwords :wink: )?

Sébastien,

Sorry for the delay in replying.
Well there is a lot of work here

I tested on Linux and Windows.

It worked perfectly.

I have another scenario here:

The “receiver Orthanc” is behind a proxy server (Nginx with SSL).

Example: “sender Orthanc” —> HTTPS ----> NGINX —> HTTP —> “receiver Orthanc”

Return:

Sending a packet of 1 instances

I have not had time yet to configure SSL-Offloader.

Soon I will share the experience.

Thank you very much, Sébastien.
