Abstract
A method of removing air from a flow path of a medical fluid injection system is described. An exemplary method performed by the medical fluid injection device includes delivering a first amount of fluid to a fluid flow path, isolating fluid flow along the flow path, forming a vacuum condition upstream of the fluid isolation, re-establishing fluid communications along the flow path, and delivering a second amount of fluid to the flow path.
