Abstract: A system and method for correcting a volume of fluid delivered by a fluid injector during an injection procedure is described. The method included determining and compensating for a volume factor associated with compliance of the fluid injector system and correcting for the volume by one of over-driving the distance that the drive member travels in a fluid reservoir, under-driving the distance that the drive member travels in the fluid reservoir, or lengthening or shortening a fluid delivery time.

Abstract: The present disclosure provides improved methods for calibrating the zero position of at least one drive member of an injector system is disclosed. Automated methods of position calibration of the drive member of a fluid injector are disclosed. These methods address sources of error in positional accuracy and fluid delivery inaccuracies, such as disposable syringe tolerance and injector wear over time. According to other embodiments of the present disclosure, methods and fluid injector systems for determining and correcting for the amount of slack in a fluid injection apparatus are described. An understanding of the calibration and the amount of slack in a fluid injection system allows a processor to correct for the slack, thereby ensuring more accurate fluid delivery to the patient and more accurate imaging processes.
