medInria images retrieveing problem

[Deya El Halabi]

Hello,
          I  can query the  images from orthcan pacs, but unfortunately I  can't retrieve them. I  did all my best in order to fix  this problem but I  can't find a solution.
Note: I have attached a screenshot of my conf.
Regards,

[Sébastien Jodogne]

And what is the configuration of Orthanc?

Please carefully follow the "troubleshooting DICOM" guide of the Orthanc Book:

Also, please do not open multiple threads about the same topic:

Seems like MedInria does not support JPEG 2000.

Hello,
          So  what  can I do in order to handle this problem, the developer of orthanc have said   that orthanc works smoothly with medinria.

That is a problem with the way the specific dicom images you are trying to retrieve are encoded and Meinria, not Orthanc.
If you tried to send these images directly to Medinria, without orthanc, the same problems would ensue.

As far as I'm aware Orthanc does not have (yet?) encoding conversion capabilities. 

So your options are to:

Fix the encoding at the source (if possible it is by far the best option), change the modality encoding options;

Use some other pacs that has the capability to reencode the images, with JPEG 2000 there are a lot of problems with those but it is possible;

Design a script, Lua or external (python would be my choice), to get the images, re-encode, resend to Orthanc and then to Medinra. This will take some work, but if the first option is not viable it would solve everything without another install and configuration.

I fully agree with Chico's and Robert's answers: medInria does not seem to able to receive DICOM files encoded using the JPEG2000 transfer syntax through the DICOM network protocol.

This is not a problem on the Orthanc side, especially if such network transfers work fine with RadiAnt, as you reported here:

https://groups.google.com/d/msg/orthanc-users/AHx5swG293o/Jeb7NDk7DgAJ

You must be aware of the fact that even if Slicer/medInria are able to open JPEG2000 DICOM files on the disk, this does not imply that they can receive files through the DICOM network protocol. Please get in touch with the community of these projects to know more about this topic, we cannot answer on their behalf.

As far as I'm aware Orthanc does not have (yet?) encoding conversion capabilities.

We are indeed currently working on the possibility of creating plugins to transparently transcode DICOM files to other transfer syntaxes if required as part of a C-Store.

 

So your options are to:

Fix the encoding at the source (if possible it is by far the best option), change the modality encoding options;

Use some other pacs that has the capability to reencode the images, with JPEG 2000 there are a lot of problems with those but it is possible;

 

For this to work, you might also have to set the "Jpeg2000TransferSyntaxAccepted" configuration option of Orthanc to "false", so as to prevent your original PACS sending JPEG2000 images to Orthanc, and to force the original PACS to transcode the images:
