|
Create net dumps |
Enabled | Net dumps are created when the viewer encounters a network problem. As these errors have a tendency to happen multiple times in a row, the corresponding logs usually contain redundant information. Consider disabling net dump sending to preserve server storage and network bandwidth | %LOCALAPPDATA%\eRAD PACS Viewer\Logs | netDump-<yyyy>-<mm>-<dd>--<24hr>-<min>-<sec>.txt |
| Maximum age of unsent log files (in days) | 30 | Log files older than the specified age are automatically purged. If set to 0, log files are kept indefinitely. | ||
| Maximum age of sent log files (in days) | 3 | Log files sent to the server are purged if they're older than the maximum age. If set to 0, sent log files are kept indefinitely. | ||
| Maximum number of log files | 25 | If the number of log files in any category (session, crash, net) exceeds the maximum amount, the oldest log is purged. Set to 0 to allow any number of log files. Applied on a per category basis. |
| General Settings | Default | Description |
| Enable standby mode | Enabled | If the standby mode was enabled, the viewer won't be closed when the frames are clicked closed. The viewer will only be visible on the taskbar. |
| Show tooltips | Enabled | Tooltips are popup text strings that help identify the functions of a tool. When enabled, tooltips appear after you place the cursor over a button, field or gauge in the viewer. When disabled, no tooltips appear. |
| DICOM image tagging | Enabled | When the server is configured to support image tagging, updated objects will be reloaded from the server rather than from cache. |
| Group 4D seriess | Disabled | When enabled, series with multiple acquisition times are grouped into a single series on the thumbnail panel. A clock icon appears in the top, left corner of the thumbnail image to indicate timed sequences exist. When disabled, each series appears separately on the thumbnail panel and no clock icon appears in the thumbnail image. |
| Web control | Internet Explorer | When configured for Internet Explorer, viewer web pages (eg, the patient folder) use Microsoft web control. When configured for Edge, viewer web pages use WebView2 controls. A viewer session restart is needed to take effect. |
| Group 4D series | Disabled | Group series by phase when loaded into the image frame. When disabled, they are grouped by location as defined by the imaging modality. When enabled, images are grouped by time, displayed one phase after the other and show a clock icon in the top, left corner of the thumbnail. |
| Cache settings | Default | Description |
| Clear cache | None | None: Cached data is not removed upon viewer exit or sign off. Exit: Cached data is removed before exiting the viewer from the system tray. Sign Off: Cached data is removed when the user signs off the system or exits the viewer from the system tray. |
