At one point, I wrote down a couple of note on 'how to write DICOM':
the page is rather messy and difficult to read unfortunately :(
Anyway I would suggest to avoid DERIVED, simply use SECONDARY as Image
Type. I would also try to avoid Secondary Capture as they do not have
Image Position (Patient) / Image Orientation (Patient). There are new
classes of Secondary Capture that support multiframes, but my
definition of 'volume' is slightly different: I need world position
(this could be enough for your use case though).
