If you have not built Slicer yet then and don’t want to do it just for this then we can help you with that.
I had a closer look at CreateDICOMSeries.cxx and it actually saves window center and width fields (although it sets is to the cover the full intensity range of the image, which is not ideal):
Could you check why that particular device may reject the image? Maybe the field is there but the data type or value is incorrect?
