Abstract: A method of maintaining an overall flow rate during a sequential delivery of at least two fluids to a patient’s blood vessel includes delivering at least a first fluid into the patient’s blood vessel at a first flow rate, delivering at least a second fluid into the patient’s blood vessel at a second flow rate, and adjusting at least one of a first flow profile of the first flow rate and a second flow profile of the second flow rate to dampen a transient increase in the overall flow rate during a transition between delivering one of the first fluid and the second fluid to delivering the other of the first fluid and the second fluid.

Abstract: A plunger cover for use with a syringe includes a sealing portion adapted to form a seal with the syringe and a central portion adapted to contact fluid within the syringe. The central portion can, for example, be more rigid than the sealing portion. The sealing portion and the central portion are connected in an overmolding process. The sealing portion can, for example, be formed from a thermoplastic elastomer or a thermoplastic polyurethane. The central portion can, for example, be formed from polypropylene, acrylonitrile butadiene styrene, polycarbonate or copolymers thereof.

Abstract: An engagement mechanism associated with a reciprocally movable piston of a fluid injector is configured for releasably engaging an engagement portion at a proximal end of a rolling diaphragm syringe having a flexible sidewall configured for rolling upon itself when acted upon by the piston. The engagement mechanism has a plurality of engagement elements reversibly and pivotally movable about a pivot pin relative to the engagement portion of the syringe between a first position, where the plurality of engagement elements are disengaged from the engagement portion of the syringe, and a second position, where the plurality of engagement elements are pivotally movable about the pivot pin in a radially inward direction to engage with the engagement portion of the syringe. The engagement mechanism further has a drive mechanism for moving the plurality of engagement elements between the first position and the second position.

Abstract: A medical injector including at least one syringe port for engaging at least one syringe and having a locking mechanism. The locking mechanism enables the syringe to self-align with the syringe port for locking engagement upon insertion of the syringe into the syringe port and to axially eject the syringe from the port upon rotational disengagement of the syringe from the port.

Abstract: A fluid injection system and a fluid verification system for determining the operating status of the fluid injection system, for example by confirming that a fluid reservoir, containing a fluid for injection, is fully filled with fluid and 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, methods, and systems are also provided to determine various injection parameters and to verify the type and certain properties of fluid that is present within the fluid reservoir.

Abstract: Described is an in-scan phantom for use during an imaging procedure. The phantom can include at least one measuring insert and/or at least one measured insert. The measuring insert may have radiation detecting capabilities while the measured insert may include a radioactive material. Also described is an imaging modality system that includes an imaging modality and an in-scan phantom as well as methods of using the in-scan phantom for imaging a patient or performing a scout scan.
