Yes, we should really wrap that one up - basically we just need to look for the WindowCenter/WindowWidth tags in the dicom header and put them in the display node. It should go in the slicer4 DICOMScalarVolumePlugin (and maybe other plugins?).

Here's the slicer3 code for that around line 676:

I'll add this note to the issues.

Steve: "It might be good to look if we should add this to the volume storage node instead of the dicom module (so dicom data loaded via Add Data would also have the presets)."

I implemented the window/level read and apply in the scalar volume plugin as originally discussed, see
https://github.com/cpinter/Slicer/tree/3467-read-and-apply-windowlevel-from-dicom

I looked at the volume storage node, but there was no trace of using any DICOM information there, so it was far from straightforward to add this. If it's needed then we have to discuss it more. Otherwise we can just integrate the above branch.

What you did makes sense to me. I made one in-line comment to the code which you can either ignore or turn into a comment if you don't think it's worth addressing (I don't think it's a high priority - what you have done so far should handle > 99.9% of cases.)

Thanks Steve! I added your comment and committed the changes
