Be glad for DICOM. In digital pathology we don't even have that. Every manufacturer has their own format. We don't even have proper OS libraries, there is a LGPL library that hasn't been updated for 2 years and GPL one that's up to date but slow as molasses.

EDIT: yes, I meant OpenSlide and BioFormats. BioFormats is in unoptimized Java. Oh yeah, and DICOM for pathology exists and some software tools use it exclusively but none of the manufacturers do. As the only standard some organization press for standardizing on it - forcing all vendors to provide convertors. But those are often slow, buggy and produce huge files.
