If you want all the gory details about the DICOM curve, the full DICOM
specs are available via David Clunie's web site (www.dclunie.com).
Follow the "DICOM standard status" link and then look up the document
called PS 3.14, "Grayscale Standard Display Function".
(I used to work in medical imaging, and while it was both fun and
interesting, my spontaneous advice to anyone encountering DICOM for
the first time is "turn and run!" :-) )
