eRAD PACS Operator Manual 7.3.9 LISTING PRIORS SETTINGS The list of relevant priors displayed by clicking to open a study include entries resident in the configured archives if the Priors setting is set to search the archive. By default, the relevant priors search includes only eRAD PACS. The admin can change the default setting to include all configured archives. The setting for including the archive when searching for relevant priors is on the Settings page, under the Admin tab. In the section labeled Prior Settings, check the Enable LocalOnly Version of Prior Page to exclude remote archives when looking for prior while opening a study. When local-only searches are enabled, the search button, , exists on the worklist for searching third-party archives manually. Querying third-party devices may take some time to complete. If no priors are found, the search unnecessarily delays loading data into the viewer. If the only archives connected to the server are third-party devices, using the local-only setting is recommended. 7.3.10 CHANGE STATE SETTINGS The Changed State flag is a worklist parameter used to inform the user that the study has been modified since its state was last updated. It is a worklist field available for filters, plus it changes the icon used for the Open button depending on the configured setting. This setting is in the Change State Settings section of the Settings page. It is displayed for users with support privileges. The setting can be None, newOnly or anyChange. None disables the change state feature. It is the default setting. NewOnly means the study acquired a previously unregistered object (e.g., an image) since the last state or report change. AnyChange means the study data has been altered in some way (e.g., edit patient name) since the last state or report change. 7.3.11 DATA PURGING SETTINGS By default, eRAD PACS manages the disk usage automatically, but it never removes primary image data, report data or orders unless the administrator explicitly instructs it to do so. Even then, eRAD PACS only does so when it needs additional disk space. This means no purging occurs until the Free Space Limit (see section 7.3.5 Disk Limit Settings) is reached, even if a study is older than the specified purge period. All purging will be processed during off-peak hours, usually in the early morning. Therefore, after you change these settings, you must wait until eRAD PACS runs the purging process before the settings take affect. Stopping and restarting the server will not invoke the purge process. To set the purge rules, go to the Settings page, and scroll down to the Regular Tasks section. Only users with support rights can edit these settings. There are four options to specify: • • • •
Purge Regular Studies: maximum number of days a study will exist on the server. Purge Preliminary/Final Studies: maximum number of days Preliminary or Final state will exist on a server. Purge Orders: maximum number of days an expired order remains in the worklist. Keep New Studies For: number of days a study must exist on the server before it can become eligible for purging.
