You can remove any type of registration for any active datasets, groups, or series in two or more studies.
Important: You can only remove the registration between the active group and the other groups. See the example.
After you remove registration, operations are no longer concurrent between the groups. For example, the scrolling and swiveling actions do not occur simultaneously between the groups.
1. View an active, registered group in a study containing volumetric data.
2. Click Register Studies 
to view the drop-down menu.
3. Click Break Registration 
.
4. Repeat steps 1 to 3 until you have removed the registration for all the desired studies.
