An injection system for delivering a pharmaceutical fluid to a patient via an injection procedure performed in connection with an imaging procedure, the imaging procedure being performed with an imaging system comprising a scanner having at least one x-ray tube, the injection system comprising:a parameter generator programmed for determining parameters of at least a first phase of the injection procedure wherein at least one of the parameters is determined on the basis of a voltage to be applied to the at least one x-ray tube of the imaging system during the imaging procedure,wherein the parameter generator is programmed to determine at least one of a volume of the pharmaceutical fluid to be injected during at least the first phase and a flow rate of the pharmaceutical fluid to be injected during at least the first phase on the basis of the voltage to be applied to the at least one x-ray tube during the imaging procedure, andwherein the parameter generator is programmed to determine the volume of the pharmaceutical fluid to be injected during at least the first phase by adjusting a volume parameter of a baseline injection protocol,such that the injection system delivers the pharmaceutical fluid to the patient during at least the first phase of the injection procedure according to the determination of the volume of the pharmaceutical fluid to be injected during at least the first phase.
