We are working on an MRI system producing individual DICOM files for each slice in a particular orientation. We are having trouble displaying the cross-reference line (yellow line) when 2 series for the same study is loaded.

Things we have tried so far, (for each image)
Added the Image Patient Position,
Image Patient Orientation,
Pixel spacing,
Slice thickness,
Same study Instance UID,
Same frame of reference UID,
Same Study Id,
Sequenced instance number,
Same Study description,
Sequenced Series number,
Different Series Instance UID

With the above changes we are not seeing the cross-reference line unfortunately. Are we missing something?

Thanks
