Abstract: A fluid injector system has a controller for operably controlling the injection of contrast and/or saline into a patient. The controller allows a user to program a diagnostic injection procedure having one or more phases according to which the contrast and/or saline will be injected into the patient so as to effect enhancement of a region thereof during an imaging procedure. It further allows the user to program a test injection procedure to be performed prior to the diagnostic injection procedure. The test injection procedure is implementable as: (a) a variable single phase test injection in which the rate at which the saline is to be delivered is selectable prior to and may be varied during performance thereof; and/or (b) a multi-phase test injection in which the rate at which the saline is to be delivered is selectable for each phase of the multi-phase test injection prior to performance thereof.
