Dear All,

I am trying to launch Weasis from my web application. Mimicking an example given in the Weasis web site accessing Orthanc studies via dicom-web.

I tried via reverse proxy and directly but could not get the studies displayed.

Getting error in Verbose

Unsupported return MIME type: text/html, image/gif, image/jpeg, *; q=.2, /; q=.2, will return DICOM+JSON

Any idea what could be the issue?

I have attached verbose.

Hi

Looks like the QIDO-RS request has an “Accept” HTTP Header set to “text/html, image/gif, image/jpeg, *; q=.2, /; q=.2” while it should be "application/json

e.g with curl commands:

The reported accept header looks like the ones set by a browser while Orthanc shall be contacted by Weasis HTTP client that should set the Accept Header correctly. I would suggest that you get in touch with the Weasis support to get more information…

HTH,

Alain

Dear Alain,

Thank you so much for the response.

Kindly note I have attached a sample html page. It has an tag to launch sample patient directly from Orthanc-Server on my local Weasis. This works flawless. If I replace href attribute to my localhost (reverse proxy) then I was hoping that it would work as well but it does not. This means either my nginx configuration could be incorrect or my Orthanc configuration is missing something since Orthanc Web Server sample provided by Weasis works.

Any advise please?

Please note I have attached nginx configuration and Orthanc configuration.

Thank you again!!

Hello! Here is my configuration to work with Weasis. Hope it works for you.

Weasis DICOM node:

}
}

DicomWeb configuration:

“DicomWeb”: {
“Enable”: true, // Whether DICOMweb support is enabled
“Root”: “/dicom-web/”, // Root URI of the DICOMweb API (for QIDO-RS, STOW-RS and WADO-RS)
“EnableWado”: true, // Whether WADO-URI (previously known as WADO) support is enabled
“WadoRoot”: “/wado”, // Root URI of the WADO-URI (aka. WADO) API
“StudiesMetadata”: “MainDicomTags”,
“PublicRoot”: “/###PUBLIC_ROOT###/dicom-web/”,
“Ssl”: ###DICOM_WEB_SSL###,
“QidoCaseSensitive”: false // For QIDO-RS server, whether search is case sensitive (since release 0.5)
},

Since you are behind NGINX, I guess you will need PublicRoot set (see https://groups.google.com/g/orthanc-users/c/Z-GYyBiBHp4/m/85gKyDyvBAAJ). In my case, the “###???###” values are replaced at build time with Docker.
