Hi, when making a query to Orthanc DICOMweb plugin the query is taking very
long time compared to other pacs-implementations. When looking the network traffic most of the time is spent on the "waiting" state and during that time
the processor speed goes up. This imples that the conversion from DICOM
to jpg on the Orthanc is taking a long time not the actual transfer process . Is there any way to speed up the download time, i.e., do the conversion immediately when a new instance is arrived etc. ?
Hello,
Please could you give the exact HTTP request that is issued by your WADO client (as shown by your network traffic analyzer), together with a sample DICOM file you try and access?
Also, make sure you use a non-debug version of Orthanc and its DICOMweb plugin:
http://book.orthanc-server.com/faq/troubleshooting.html#performance-issues
It is definitely possible for you to create a C/C++ Orthanc plugin that would pre-generate JPEG images and store them as attachments for subsequent retrieving through WADO.

Check out “OrthancPluginRegisterOnStoredInstanceCallback()” to awake your plugin when new instances are received by Orthanc:

Hi, thanks for the reply. The http-request used is https://localhost:8043/wado?requestType=WADO&objectUID=1.2.276.0.7230010.3.1.4.296485632.1.1507285501.114332 . The DICOM zip-file downloaded from orthanc is around 7.6Mb and it exceeds the maximum size of attachment in google-groups. Is there some other way to post the DICOM file?
The dicom-file can be downloaded from the following github url https://github.com/vili22/dicomfiles/blob/master/c33e4fea-ddfb8f0c-38a82815-260418fc-f6fcc6eb.zip
