The Roles page has the following fields:

The CanChangeServerSettings permission does not include Patient Updater or image deletion privileges.

The CanDeleteFromDatabase permission grants deletions on a case-by-case basis (no mass deletions).

The CanEmptyDatabase permission grants deletion of the entire database. Only Administrators should have this permission, and should give themselves this permission only rarely.

The PatientUpdaterAdmin permission grants administration privileges for the Patient Updater (image and Patient Updater options alterations).

The PatientUpdaterDelete permission grants the privilege to delete images using the Patient Updater.

The PatientUpdaterEdit permission grants the privilege to edit images using the Patient Updater.

Image Level Page Size

This is the maximum number of records displayed on a single page in the Database Manager.  When Display is Image Level, all pages except the last one will contain exactly the specified number of records. The last page will contain the remainder. If Display is Patient Level, Study Level, or Series Level, then the number of records in each page can be less than the Image Level Page Size.
