DICOM images look fine on CR workstation but have white stripes on exported DICOM

[Sistema CLINSIS - Cedric Simon]

DICOM images look fine on Fuji CR workstation, but have white stripes on exported DICOM to DCM4chee.

I do not have this issue on Agfa CR, nor on US, CT or MR.

Does anybody have had same issue, or have an idea of what could cause this? How could I fix it?

Any suggestion is welcome.

Many thanks in advance.

No expert but looks like the grid?

Input from another forum: "I'm quite sure the stripes are some scanning artifact, as they are not symmetrical (can be seen in the lower left), and this is an issue with the VOI LUT, so the only way to "fix" this would be to use a better LUT.". Any idea how to "fix" this. I have no idea what VOI LUT is exactly and how to modify it.

By the way, we discover that MG images are transmitted without issue (perfect image), but CR are giving the stripes issue. Same digitalizer, same workstation and software.

Look closer on your "CR Workstation"

That sure looks like acquisition artefact.

DICOM images look fine on Fuji CR workstation, but have white stripes on exported DICOM to DCM4chee.

I do not have this issue on Agfa CR, nor on US, CT or MR.

Does anybody have had same issue, or have an idea of what could cause this? How could I fix it?

Any suggestion is welcome.

Many thanks in advance.

Will do. We suspect the issue is the cassette,not DICOM issue, since RX on Agfa CR is fine, and MG on Fuji is fine too. Only CR on Fuji has issue.
