Question Posted 10/20/14:
I used the Advanced Search (beta) function to find images, and display their stduy group. The results only show the Patients study group. Is it possible to access the Volunteers' images?

All the images correspond to 'patients'. You may search by diagnosis ('DX Group' category) which does include a control group.
