Abstract
A fluid injector system includes a control device operatively associated with a first drive component configured to pressurize and inject a first fluid and a second drive component configured to pressurize and inject a second fluid. The control device includes at least one processor programmed or configured to: during a first phase of a multi-phase injection protocol, actuate at least the first drive component to inject the first fluid; during the first phase of the multi-phase injection protocol and prior to transitioning to a second phase of the multi-phase injection protocol, actuate the second drive component to pressurize the second fluid relative to a pressure of the first fluid; and during the second phase of the multi-phase injection protocol, actuate the second drive component to inject at least the second fluid so that a desired steady-state ratio of the first fluid and the second fluid in the second phase is reached.
