    Dear Kashif


    The logs showed that everything is working fine.


    1) Viewer is plugin appropriately initialized. So viewer is downloaded.

    2) WADO query is also OKIE

    3) Weasis manifest file is also created.

    4) Series are loaded


    There is a connection error as indicated in the logs. If possible can you share the logs for review.


    I would recommend that instead of using native viewer call why don't you shift to newer one. I am hopeful that it would solve your problem. :)


    Otherwise, did you try to create the manifest file manually and check; were you able to view study or not????


    --HM

    Hi,


    Did you check the contents of the manifest? The refusal suggest the manifest file contains incorrect links. Buy I have not used weasis for a while, having just developed DICOMweb and ohif. Maybe weasis can use DICOMweb?

    Hi,


    I just downloaded weasis 4.1.2 and tried it with conquest1.5.0d. The C-GET interface works fine and loads images very fast.




    The web interface does not seem to work very well. It loads slowly and then the images do not show up.





    I am not sure what causes this. I also tried the built-in webserver (localhost:8086) but that works even less, no search results are shown. Both work fine with OHIF and pass tests in http://localhost:8086/api/dicom/test.html.

    Hi,


    I have updated two Lua files on git to correct subtle syntax error in conquest's web responses. Weasis now works with dicomweb (both in PhP and Lua modes). The new files must be updated in the dicomserver folder for Lua mode, and in your Apache htdocs folder for PhP mode.


    Marcel

    To start a recent Weasis from newweb, update the two files as listed above, install Weasis, and add this line to your app/newweb/dicom.ini under section [webdefaults].


    Code
    studylink = '<TD><A href=weasis://%24dicom%3Ars%20--url%20%22http%3A%2F%2F127.0.0.1%2Fapi%2Fdicom%2Frs%22%20-r%20%22studyUID={StudyInstanceUID}%22>Weasis</a>'



    This is a link as documented here: https://weasis.org/en/getting-started/weasis-protocol/


    Viewing at series level is set as follows:


    Code
    serieslink = '<TD><A href=weasis://%24dicom%3Ars%20--url%20%22http%3A%2F%2F127.0.0.1%2Fapi%2Fdicom%2Frs%22%20-r%20%22seriesUID={SeriesInstanceUID}%22>Weasis</a>'


    Note that the links inside the Weasis command must be absolute and must therefore be edited to replace e.g. http://127.0.0.1 with http://127.0.0.1:8086 (for Ladle server) or http://yourhostname.
