the scan immediately regardless of you pressing "OK," "Same Patient," or "New Patient" on the
injection complete window.
It is recommended not to program Hold phases in the injection protocol when using the ISI
feature unless directed by the scanner manufacturer. If the scanner manufacturer does not
support sending a (re)start request to the injector in the Hold phase, it will require you to press
the start button manually on the injector to exit the Hold phase and continue the injection
protocol. Contact your scanner manufacturer to determine if it supports the restart from Hold
feature.
NOTE: The scanner manufacturer and/or user make the final determination
of the mode of operation for the interfaced injector and scanner. The
scanner manufacturer is responsible for providing operation
instructions for their system.
For Certegra Workstation, some behaviors of the injector head arm indicator lights (the blue
and green indicator lights around the manual fluid movement knobs) have been modified.
In independent and monitored operation, where the injector cannot request the scanner to
start, the arm lights on the injector head flash once per second when the injector is armed.
In coupled operation with the scanner where the injector may request the scanner to start (the
injector will be labeled as described in the symbols section), the arm lights flash approximately
twice per second with a "short flash, long flash" pattern.
1. Program the scanner. You will see the ISI Ready icon
2. Program the injector.
3. Arm the injector.
NOTE: For specific information about programming, arming and injecting,
refer to the specific injection system Operation Manual.
4. Execute procedure.
• Press start switch on either scanner or injector to enable the scan/inject
sequence.
If you are starting the procedure from the injector the following applies.
1. If a "Test Inject" is selected on the injector, the scanner will not be Requested to Start
when the test inject is being initiated. The injector will inject the test bolus as programmed,
and then go into an automatic Hold which is part of the "Test Inject", but the scanner will
not be requested to start.
2. Once the Test Injection is determined to be "normal," the next step would be for the user
to depress the Start Switch again, which would start the injection of the primary bolus. It is
at this time of the second start switch depression that the scanner would be Requested to
Start.
If a Hold is manually programmed into any phase of the injection protocol, the ISI will treat them
as a standard injection phase (the "Request to Scan" command will continue to be given during
the Hold and Pause phase).
NOTE: It is not recommended to program a Hold phase into an injector
protocol unless the scanner supports the "injector ready" functionality.
Otherwise, to continue the injection from a Hold phase you must
manually press start on the injector to exit the Hold. To find out if the
scanner supports the "injector ready" functionality, contact your
scanner manufacturer.
when the scanner is ready.
