    Any plans to support calibration to DICOM GSDF – that would be great. Or does anyone know a method?

    DICOM support is planned for Argyll CMS I think, although I don’t know if and when that’ll happen. The Argyll CMS mailing list is probably a good place to ask about it.
    There’s also (limited) support for DICOM in DisplayCAL, i.e. you can create synthetic profiles with DICOM transfer curve if you know your display’s white and black level. Such a profile can then be assigned to DICOM material and should give the correct appearance in color managed applications if the display is appropriately profiled as well.

    Thanks, that requires each dicom file (thousands) to have that profile embedded?

    I found one program that uses Spotread from Argyll cms, but it doesn’t work on Windows 10. It is: http://pacsdisplay.org/ and is open source. Could DisplayCal replace this someday? And even do better by adding support for 1024 greyscales!? (At work our DICOM files are displayed on 10 bit systems, from graphics card, application, to monitor, so 256 greyscales is a bit of a downgrade!)

    I suspect if I had more brain I could do it all from the command line with Argyll and Spotread, and then use the bits of Pacsdisplay that do work on Windows 10, but that is beyond me, so I thought I try and ask to see if DisplayCal could do it.

    Not necessarily, depending if your image viewer allows to set a default profile to be used for files with no embedded profile.

    Sure, after DICOM has been added to Argyll CMS.

    And even do better by adding support for 1024 greyscales!?

    The amount of grayscale levels is only limited by the graphics subsystem (graphics card / driver / application).

    Thanks, it is shame the PACS (essentially the image viewer) doesn’t cater for profiles. I have asked on the Argyll mailing list.
