Abstract: A system for controlling a fluid injection system is disclosed. The system includes at least one processor programmed or configured to determine at least one characteristic of a power injection protocol, where the at least one characteristic of the power injection protocol is associated with a medical fluid involved in the power injection protocol, determine an estimated value of viscosity of the medical fluid based on the at least one characteristic of the power injection protocol, calculate a hydraulic resistance score based on the estimated value of viscosity of the medical fluid, and determine one or more motor controller gains of a motor of a powered fluid injector in the power injection protocol based on the hydraulic resistance score.

Abstract: A pressure jacket configured for connecting to an injector head of a fluid injector has an open distal end, an open proximal end, and a sidewall defining a throughbore extending between the distal end and the proximal end along a longitudinal axis. The throughbore is configured for receiving at least a portion of a syringe. The pressure jacket has at least one syringe retaining element positioned at least partially within the throughbore. The at least one syringe retaining element is configured for engaging at least a portion of the syringe during pressurized delivery of fluid from the syringe to prevent or limit a distal movement of the syringe relative to the pressure jacket.

Abstract: A method, system, and computer program product are disclosed for performance monitoring of a smart fluid injector system having at least one sensor configured for detecting operation data. The operation data includes one or more operation parameters associated with at least one of: one or more drive components of the fluid injector system and at least one disposable component configured for use with the fluid injector system. The fluid injector system further includes a control device having at least one processor programmed or configured to: receive the operation data, and determine a component status for at least one of: the drive component(s), the disposable component(s), and administration line(s) by comparing the received operation data with stored operation data. The component status includes one or more predictions of an operation failure or a misuse of at least one of: the drive component(s), the disposable component(s), and administration line(s).

Abstract: A fluid injector system includes at least one fluid reservoir having at least one interior surface and defining an internal volume, at least one actuator configured to change the internal volume of the at least one fluid reservoir, and at least one processor. The at least one processor may be programmed or configured to drive the actuator to at least partially fill the at least one fluid reservoir with a fluid from a fluid source, drive the actuator to generate a least a partial vacuum within the internal volume to dislodge one or more gas bubbles adhered to the at least one interior surface and to cause the one or more gas bubbles to coalesce into a coalesced bubble, and drive the actuator to expel the coalesced bubble from an outlet of the at least one fluid reservoir.

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 method for determining a volume of one or more air bubbles in a fluid path includes initiating an injection procedure in which at least one medical fluid is injected into the fluid path, receiving an electrical signal from an air detector of the fluid injector system, wherein the electrical signal indicates the presence of one or more air bubbles in the fluid path, calculating a flow rate of fluid in the fluid path, determining a fluid pressure in the fluid path, determining a count value of the one or more air bubbles representative of a volume of the one or more air bubbles, and updating a cumulative counter with the count value of the one or more air bubbles. The cumulative counter is representative of a cumulative volume of air that has passed through the fluid path during the injection procedure.

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: A system and method are disclosed for user- or system-configurable and adaptive pressure limiting behavior in fluid injection systems/devices. A fluid injector system may include at least one fluid injector device, at least one user interface, and a control device comprising at least one processor. The at least on processor may be programmed or configured to: receive a maximum pressure limit for an injection procedure, receive a programmed fluid flow rate for the injection procedure, receive a maximum fluid flow rate reduction input for the injection procedure, wherein the maximum fluid flow rate reduction input is selected by a user via the at least one user interface, and receive a pressure limit sensitivity input for the injection procedure, wherein the pressure limit sensitivity input is selected by the user via the at least one user interface. The at least one processor may also be configured to control the at least one fluid injector device to perform the injection procedure based on the maximum pressure limit, the programmed fluid flow rate, the maximum fluid flow rate reduction input, and the pressure limit sensitivity input.
