System Management

 

Under normal circumstances, the eRAD PACS viewer handles all the routine maintenance and system management functions. Nevertheless, a number of tools exist for manually verifying or overriding the viewer’s regular procedures.

 

Licensing

 

The use of the eRAD PACS viewers require a valid license which are customized for and installed on the server. When the user logs into eRAD PACS, the server checks that the license is installed and permits the operation requested. Administrators can review the licensed components in the User License Information section of the Server web page.

 

Plug-in licenses are managed separate from the basic and workstation licenses. A user is licensed to use the specified plug-in module if the server the user is logged into has the plug-in license installed.

 

Note: Since the plug-in license is server-based, a user may have access to the plug-in module when logged into one server but not have access when logged into another.

 

Permissions (Open Rights and Report Rights)

 

Use of the viewer is a privileged operation. To invoke the viewer, the administrator must have assigned Open rights to your account. If a notification is received when attempting to open a study in the viewer informing the user that they are unable to access the viewer application, the system administrator must be contacted to request Open privileges.

 

The viewer has the ability to edit reports which require Report rights.

 

These abilities include:

 If you are unable to save changes made to the study from the eRAD PACS viewer, contact your system administrator and request Report privileges.

 

Network Transfer Optimization

 

There are specific settings best suited for data downloads under specific area networks.

These settings for optimized data download include:

eRAD PACS automatically sets these settings based on its configuration and on measured feedback it obtains during each download operation. The user can override these automatic settings from the Settings panel under Images/Compression in the eRAD PACS viewer. The Images page contains the compression setting for download of the study summary information, and the packet size for all transfers. The Prefetch and Image pages control the compression setting for the download of the image data. When set to Auto, these settings are dynamically set based on the eRAD PACS LAN domain setting, plus the measured feedback eRAD PACS obtains during each download operation. In almost all situations, Auto yields the best overall download performance.

 

eRAD PACS supports settings to define what address ranges constitute the local area network which are defined in the LAN domain field on the server’s Server web page. Any IP address not on this list is deemed accessible via a wide area network. eRAD PACS uses these settings to automatically adjust the compression setting and the initial network packet sizes for data transfers between its server and viewer.
