DICOM BUG ($88,$0200) preview

[DOS386]

Problems with DICOM in NC 6.17 (there is no latest, and most of it affects XNview too):

- If DICOM file contains a preview image (element ($88,$0200) SQ), NC takes only this one, instead of the main image. I can "fix" it by "patching away" the "evil" element. Solution: skip this element when searching for the image.

- NC "-info" reports 8 bits per component, despite it's more

- NC "-info" reports some of the medical junk, but doesn't report the bit stuff (location of the usually 12 useful bits within the usually 16 total bits)

- some files give garbage when viewed or converted (needs more investigation)

could you send me samples?

could you send me samples?

Unfortunately the "samples" are highly private and sensitive and thus not redistributable ... but I had already investigated the BUG finding out that the element ($88,$0200) is source of the problem. Also, I have for now no easy way to sufficiently anonymize the samples or to brew artificial samples exposing this BUG

The 2 problems with NC "-info" can be probably reproduced with any common 12 bpp DICOM file.

OK I found a public example (3.3 MiO):
