Corrupted images when sending from GE Prospeed scanner

[AndreasKnopke]

Hello Offis Team,

I encountered as strange communication problem with an old GE ProSpeed scanner and the Offis StoreSCP (a slightly modified version based on 3.5.3 shipped with K-PACS).
When sending from the scanner the StoreSCP receives the data without error messages but the pixel data seems to be corrupted. Have a look at the two sample images ( http://www.k-pacs.de/GE-PROSPEED1.dcm ; http://www.k-pacs.de/GE-PROPSPEED2.dcm). K-PACS and DICOMScope display them the same way.

The strange thing is that when sending these images from the scanner to an E-Film workstation and then forward them to K-PACS, everything displays ok.

Any idea?

Best regards,
Andreas

I haven't had time to look at the image (I'm not in the office this week), but there is one known bug in various older GE scanners that might be the cause of this problems: These machines happily negotiate Explicit VR transfer syntaxes, but then send images with incomplete/damaged pixel data. If one forces the system to send in Implicit VR (using the --implicit command line option), everything works as expected. This is certainly worth a try.
