7-4-2 Disruptive mode
Disruptive mode is a way to control interruptions to operation of
the Vivid T9/Vivid T8 . Disruptive mode is required whenever
service performs a function that may disrupt a normal scan.
Activating Disruptive mode results in a red message displayed
on the task bar. This message indicates that the Vivid T9/Vivid
T8 needs to be restarted once the service activity is complete.
The message remains until the Vivid T9/Vivid T8 is restarted.
This prevents patient scanning while the Vivid T9/Vivid T8 is not
operating at an optimal status. For example, running a
diagnostic may leave the Vivid T9/Vivid T8 in a state that is not
good for imaging.
Specifically, Disruptive mode is required to run diagnostics,
clean presets, and reset the patient database, and turn on
Virtual Console Observation (VCO).
• When Disruptive mode is On, all service functionality on the
Service desktop is allowed but user operation of the Vivid
T9/Vivid T8 may be limited.
• When Disruptive mode is Off, some service functionality on
the Service desktop is not available and user operation of
the Vivid T9/Vivid T8 is normal.
Additionally, the ability to enable Disruptive mode depends on
the logged in user.
• Local user - a user locally logged into the machine will be
able to set the Vivid T9/Vivid T8 to Disruptive mode or allow
a Disruptive mode request from a remote user through the
Service desktop. The local user must have Authorize
Remote Service Access to allow Disruptive mode. If the
local user does not have this right, the remote user’s
request will be automatically denied
• Remote user - a user remotely accessing the Vivid T9/Vivid
T8 will not be able to automatically switch Disruptive mode
to On. The logged in user (user actually logged on to the
Vivid T9/Vivid T8 ) needs to have the ability to grant remote
access. The logged in user will be notified through a dialog
box and asked to allow Disruptive mode.
NOTE: Change Password and Disk Defragment are not available
for the remote user whether Disruptive mode is On or Off.
