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.
