• Super-User/Administrator 'root' has all of the above privileges.
• All patients/studies stored in PacsOne database are Private when they're received. Only users with 'Modify' privilege can change a patient/study from Private to Public, or vice versa.
• Public patients/studies can be viewed by any user, but Private patients/studies can only be viewed by users with 'View' privilege.
• Changing a patient from Private to Public will implicitly change all studies of the patient to Public, regardless of their previous settings.
• Changing a patient from Public to Private will implicitly change all studies of the patient to Private, regardless of their previous settings.
• Changing a study from Private to Public does not affect the privacy setting of the patient who this study belongs to, except when this study is the only study of the patient. The patient will also be changed from Private to Public if and only if the study being changed is the only study of that patient.
• Changing a study from Public to Private does not affect the privacy setting of the patient who this study belongs to, except when this study is the only study of the patient. The patient will also be changed from Public to Private if and only if the study being changed is the only study of that patient.
• Public patients/studies can be viewed by all users.
• For Private patients/studies, if the current logged-in User does not have the 'View' privilege enabled, then the Lastname and Firstname stored in the current user profile will be checked to see if they match with either the Referring Physician Name or the Reading Physician Name. The Private patient/study is accessible if the lastname and firstname of the current user match with either the Referring Physician Name or the Reading Physician Name, or if the User belongs to a User Group that can access the private patient/study (see below).
• For Private patients/studies, if the current logged-in Group User does not have the 'View' privilege enabled, then the Group Description stored in the current Group User's profile will be checked to see if they match with the Institution Name of the private patient/study. The Private patient/study is accessible only if the Group Description of the current Group User match with the Institution Name of the patient/study.
• System Administration privilege is required in order to review, modify or delete system-level configuration information, e.g., the System Configuration, Email Server, System Journal, System-level Job Status pages, etc.

Based on the User Administration Rules listed above, there are three (3) categories of users for PacsOne Server Premium Edition:

Category	Description
Administrator	This is the pre-defined Administrator account 'root'. There is only one such account and it is required for all user administration tasks.
System Administrators	These are the user accounts with the System Administration privilege Enabled by the Administrator. These users can access system-level configuration information such as the Email Server, System Configuration, Journal, or System-level Job Status pages, etc.
Power Users	These accounts usually have the 'Modify' and 'View' privileges enabled by the Administrator. These users can access all patients/studies stored in the PacsOne Server database, they can also modify or delete existing database records.
Regular Users	These accounts do not have the 'Modify' or 'View' privileges and they are usually created for the referring physicians or reading physicians. These users can only read existing database records but can not modify them, they can access only those Private patients/studies with matching Referring Physician Name or Reading Physician Name.

• Search by Patient ID, Patient Name
• Search by Study ID, Study Date, Study Time, Accession Number
• Search by Series Date, Series Time, Modality
• Wild-card characters '*' and '?' can be used and the search results depend on whether the remote Query/Retrieve SCP supports the wild-card character matching method or not.

• Route By Source AE Title:
  When an image is received from a source AE, if the Source AE Title matches with one or more entries defined in the automatic routing table, then the received image will be forwarded automatically to one or more destination AE(s) defined for the matching source AE title, based on the specified schedule, which can be either as soon as received (Immediately), between a [From, To] window, or a 24-hour clock interval, e.g., 7:00 P.M.
• Route By Key Attributes:
  Users can also define a Matching Pattern String with wild-card characters like '*' and '?' for routing by key attribute tags such as Patient ID (0010,0020), Referring Physician's Name (0008,0090), Institution Name (0008,0080), or Protocol Name (0018,1030). When an image is received from a remote AE, if the key attribute tag matches with the routing key pattern defined in the automatic routing table, then the received image will be forwarded automatically to one or more destination AE(s) specified for the matching key atribute, based on the specified schedule, which can be either as soon as received (Immediately), between a [From, To] window, or a 24-hour clock interval, e.g., 7:00 P.M.
• Automatically Purge Received Images After Routing:
  After the images have been successfully routed to the destination AE(s), users can choose whether or not to delete the received images by enabling or disabling the Auto Purge variable of the specified route entry. By default, Auto Purge is Disabled so that received images will not be purged automatically after they have been routed.

If the auto-routing did not succeed after the first try, PacsOne Server Premium Edition will retry for a maximum of 3 (default) attempts to deliver the failed images to the destination AE.
