Network Fails During Operations
If a network failure occurs during use of VisionQ or standalone
Vision, the following occurs:
• The Study List goes blank (since it comes from the server
which is no longer accessible).
• Error messages are displayed in the Sweeper log file.
• The Sweeper icon in the system tray of VisionQ changes to
the down state and a balloon is displayed for the state
change.
NOTE: Be aware that unsaved workups, reports, or jpegs may be lost
as a result of a network failure.
Try to restore the network. If the network can be restored, operations
can continue. If the network cannot be quickly restored and scanning
must continue, new scans will be safely stored locally, but will not
be transferred to the server until the connection is restored.
Therefore, new scans will not appear on the Study list, which will
remain blank. To see these new scans in the list, exit and follow the
fallback operations for VisionQ.
Limitations of Networking Support
Known limitations of networking support are:
• There is a network transfer delay between acquisition or
reconstruction, and the appearance of the study on the Study
List. Although they may not appear on the list immediately,
the images are available for review and workup on the
scanner immediately.
• There is no study locking mechanism to prevent two users
from simultaneously editing or updating the same study.
Clinic workflow must ensure this does not happen.
However, if it does occur, only workups, and not patient
scan data, are at risk of being lost.
• Unsaved workups, reports, or jpegs may be lost as a result
of a network failure that happens during the save operation.
