One possibility could be to use Wine (Windows emulator) to run the windows program present on the CD. But: Wine often has problems with graphic intense software and the chances, that this would work are rather low.
Surfing the Web showed, that there might be only one decent application to allow the same functionality than the win app.
Mango (http://ric.uthscsa.edu/mango/mango.html) is capable of displaying DICOM picture series and additionally to do additional fancy things needed by a medical doctor e.g. creating 3D models (see homepage for full functionality).
As this is a java program and does not install into the system, e.g. is not accessible via the app-menu some additional steps have to be performed.
To enable all users to access the program it has to be installed into some global folder (e.g. /opt/Mango). All other steps are same asa above. Note, that only superuser can install into /opt.
Another possible program would be Open DICOM Viewer (http://sourceforge.net/projects/opendicomviewer/) but this program only has limited functionality and cannot compare to the feature richness of Mango. As Open DICOM Viewer is a Java program as well the installation instructions above also apply to it.
