Hello Marcel,
I’m seeing a rendering issue with Conquest PACS 1.5.0f.
Images retrieved via WADO look grayscale-distorted (tonal scale compressed / wrong window), similar to the attached example. They are not simply darker; the gray ramp looks incorrect.
This occurs regardless of transfer syntax:
- Implicit VR Little Endian
- Explicit VR Little Endian
- JPEG 2000 Lossless
Opening the same study in the OHIF web viewer looks correct (proper window/level), so the stored pixel data seems fine and the problem appears limited to WADO conversion.
Environment
- Conquest: 1.5.0f
- Database: MariaDB (local)
- Viewers tested: OHIF (OK), OsiriX / direct browser download / curl (distorted)
Question
Could this be related to VOI LUT / Window translation during WADO export, or a dicom.ini or config files option that affects WADO JPEG generation?
Which parameters/converters should I check or adjust to ensure correct grayscale mapping in WADO output?
Thanks in advance for your help!
