    Abstract: An injector system for delivering a medical fluid may include at least one syringe defining a reservoir operatively connected to a piston; and at least one processor programmed or configured to, based on an air check protocol for detecting air in the reservoir, determine a baseline value comprising baseline compressibility data for the at least one syringe of the injector system, deliver the first amount of the medical fluid from the reservoir; refill the reservoir with a second amount of the medical fluid; based on the air check protocol, perform an air check pressurization sequence by gathering air check compressibility data for the at least one syringe of the injector system; and based on the air check protocol, compare the air check compressibility data with the baseline compressibility data to determine a volume of air present in the reservoir.

    Abstract: A fluid injector system includes a control device operably associated with at least one drive component for use in actuating a plurality of fluid containers in fluid communication with a patient through an administration line. The control device includes at least one processor programmed or configured to enable programming of a diagnostic injection protocol comprising one or more phases according to which at least one of the first and the second fluid containers are selectively actuatable by the at least one drive component to enable injection of at least one of a first fluid and a second fluid into the patient. The control device is further programmed or configured to enable selection and commencement of at least partial preloading into the administration line of at least one of the first fluid and the second fluid in accordance with the one or more phases of the diagnostic injection protocol.
