Abstract

Power injector control logic (110) that includes ramp-up logic (120) is disclosed. The ramp-up logic (120) controls an input signal to a motorized drive source of a power injector to advance the drive ram from a stationary state to an initial velocity that is associated with an initial flow rate(114) of an injection protocol (112) to be executed by the power injector.
