Abstract: A fluid injection system and a fluid verification system for confirming that a syringe, containing a fluid for injection, is fully filled with fluid and neither has free space (i.e., air) near the distal end thereof when the syringe is provided in an upright position nor contains air bubbles. Imaging processing techniques and systems are also provided to determine various injection parameters and to verify the type and certain properties of fluid that is present within a syringe.

Abstract: A syringe including at least one retaining member protruding radially outward relative to an outer surface of a sidewall of a barrel of a syringe is described. The syringe retaining member is configured for interacting with a locking mechanism of a syringe port of a fluid injector to releasably retain the ring. Features of the syringe retaining member allow the syringe to be axially ejected from the syringe port upon rotation of the syringe. Other features of the syringe retaining member allow the syringe to engage the locking mechanism of the syringe port and rotationally guide the syringe into self-orienting alignment with the locking mechanism.
