Hello,
In case of enhanced multiframe MRI images, every frame has his own WW & WC. The Stone Viewer read the metadata, and because it don’t find any windowing tag, uses the default values 128, 256. This forces the image rendering to use an invalid window. Once the image is downloaded, it changes to correct window.
I test the Orthanc endpoint and see that you get correct windowing. So I assume that the Stone Web Viewer is not able to read correctly the WADO metada response, but once the DICOM parser read the image file I load the tags correctly.
I think that the easy solution is to avoid the window query parameters in the URL if the web parser could not find window values.
Find attached an example.
Regards,
TK
