problems that may not be noticed in day to day operation. The following procedure represents
a suggested series of activities which encompass typical operation of the system. Read the
following procedure carefully before beginning the checkout. If problems are detected, call your
Services Representative.
NOTE: Any problems detected during this or any other procedure should be
corrected before using the injection system in patient procedures.
1. Ensure that all system safety and warning labels are in place and legible.
2. Apply power to the system.
3. Refer to the Configuration and Details of Operation sections below.
4. Verify that all displays and indicators are functioning properly.

Configuration
a. If you have the Display and Control Unit (DCU), press the setup button, below. Note
that this button is a physical, rubber button and not a touchscreen button.
b. If you have a Certegra Workstation, press the following touchscreen buttons:
Overview of Operation For the most efficient and error free operation of a CT scan, the injector and scanner should be
interfaced. Interfacing is the process by which signals are transmitted and coordinated
between the injector and scanner.
The injection system does not control the imaging system via the ISI module. The ISI notifies
the scanner of the injector status which enables the scanner to synchronize the scan timing
based upon when the injection started. The scanner controls the start of the scan sequence
after it has received the injection start status and will not start the scan unless the scanner is in
the correct state. The scanner system maintains full control of the radiation initiation.
The ISI module supports the following two methods:
1. By pressing the injector start switch the injector notifies the scanner that it can begin the
scanning sequence.
2. The scanner initiates the entire scanning sequence by starting the scanner and notifying
the injector that it can start.
At the time of installation, the scanner installer may select one of the above modes of
operation.
When the injection complete screen appears, do not press “OK” on the Display and Control
Unit (DCU), or the "Same Patient" or "New Patient" buttons on the Certegra Workstation until
the scanner is finished scanning and the procedure is complete. Doing so will send a request to
the scanner to stop the scan. If the injector disarms prematurely, it will send the request to stop
1. Configure the ISI module on the injector setup screen by first accessing Setup. To
access Setup, do the following depending on your Monitor.
i. Press this button ii. Then this button iii. Then this button
2. After installation and configuration have been performed successfully, you
will see the following icon.
3. Program the scanner. You will see the following icon when the scanner is

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.
Injector Head Indicator
Lights
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.
Details of Operation 1. Program the scanner. You will see the ISI Ready icon when the scanner is ready.
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.
Hold and Test Inject
features
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.
11
Scan Delay If the injection system software version is 17A or higher, the scan delay must be programmed
from the scanner.
ISI Module Cables Maintenance: A periodic inspection of the ISI Interface Cables is a recommended to ensure
that there are no obvious defects, such as cuts or breaks in the cable, which could disrupt
signal integrity. Ensure that the connectors are properly seated.
NOTE: Scanner specific cables are typically available from the scanner
manufacturer. Contact the scanner manufacturer for details.
