System Overview
5 - 23
5.7 Power Unit
The injection system Power Unit supplies power to the Injector Head and the Display Control Unit. As
the main communications hub, the Power Unit provides system communications to all connected
components. A green light illuminates when the Power Unit is on.
The front plate on the Power Unit contains a serviceable air filter. For cleaning instructions, see
"Chapter 15 - Cleaning and Maintenance" .
5.8 Imaging System Interface
The Imaging System Interface (ISI) allows the injection system to interface with an imaging system to
provide synchronization of an injection and an X-ray exposure. To use ISI on the injection system,
configure the system from the Display Control Unit
Options tab. See "Chapter 6 - Using and
Understanding the Display Control Unit Screen" . For more information on how ISI interacts with the
injection system, see "11.3.5 - Performing an Injection with Imaging System Interface (ISI)" .

VFlow
MEDRAD VFlow (VFlow) enables the use of Variable Flow Rate injections. In the Variable Flow Rate
injection mode, the injector automatically re-arms after each injection. A Variable Flow Rate injection
can be initiated by the Hand Controller and ranges from 1 - 10 mL/sec in increments of 0.1 mL/sec.
Variable Flow Rate is intended for use in those procedures where low volumes are injected and
Variable Flow Rate control is desired. The system has an option for receiving audible feedback when
using the Hand Controller. The feedback indicates the flow rate.
See "6.4 - Options Tab" for instructions on how to enable VFlow.
5.10 Start Switches
The injection system can be used with a hand switch, foot switch and/or hand controller. The switches
allow the operator to initiate an injection.
