OrthancError: Parameter out of range with WADO RS

[Jerome Branny]

Hi everyone,

When I try to access my orthanc DICOM-Web server via this WADO RS URL: http://localhost:8042/dicom-web/studies/1.2.826.0.1.3680043.8.654.10.2010/series/1.2.826.0.1.3680043.8.654.20.2010/instances/1.2.826.0.1.3680043.8.654.50.2010.0000000000194/rendered?viewport=63,50

I get the following error:

   "HttpError" : "Bad Request",

   "HttpStatus" : 400,

   "Message" : "Parameter out of range",

   "Method" : "GET",

   "OrthancError" : "Parameter out of range",

   "OrthancStatus" : 3,

I am using the latest orthanc version inside a docker container. Interestingly enough, if i send the same request via. Postman it works.

Any help is appreciated

Thanks in advance

regards,

Jerome

Hi,

Check the Request Accept headers. Postman use as default */* and it works fine:

 but Chrome use text/html,application/xhtml+xml,application/xml;q=0.9,image/avif,image/webp,image/apng,*/*;q=0.8,application/signed-exchange;v=b3;q=0.9.

If you copy Chrome's header and disable the default */*, you can reproduce it.

I think that is not an Orthanc's issue because the official DICOM headers are:

Accept Headers

• Category	Media Type	Support
  Single Frame Image	image/jpeg	default
  	image/gif	required
  	image/png	required
  	image/jp2	optional
  Multi-frame Image	image/gif	optional
  Video	video/mpeg	optional
  	video/mp4	optional
  	video/H265	optional
  Text	text/html	default
  	text/plain	required
  	text/xml	required
  	text/rtf	optional
  	application/pdf	optional

• Following DICOM standards, is no need for */* support but Orthanc allows that.
• Chrome's headers are not compatible with DICOM media types.

Solution: find a way to force Chrome to use a WADO valid header.

TK
