Abstract: A system and method for determining the fill volume of a fluid chamber includes a fluid injector, at least one fluid chamber in fluid communication with the fluid injector, one or more sensors positioned relative to the at least one fluid chamber and configured to detect a position of a liquid-gas interface of the fluid contained in the at least one fluid chamber, and at least one processor in communication with the sensors and the fluid injector, and configured to: determine the position of the liquid-gas interface of the fluid, calculate the volume of fluid in the at least one fluid chamber based on the position of the liquid-gas interface, and at least one of: i) display the volume of the fluid; ii) enable the fluid injector to perform an action; and iii) disable the fluid injector from performing the action.

Abstract: A method, system, and computer program product for predictive maintenance. A method may include receiving operation data associated with one or more injection systems, wherein the operation data includes one or more operation parameters associated with one or more operations of the one or more injection systems; determining one or more prediction scores for the one or more injection systems based on the operation data, wherein the one or more prediction scores include one or more predictions of one or more operation failures or misuses for the one or more injection systems; and providing maintenance data associated with the one or more operation failures or misuses, wherein the maintenance data is based on the one or more prediction scores.

Abstract: A fluid injector system for delivering a multi-phase fluid injection to a patient and methods of fluid delivery is disclosed. Methods of creating and using a multi-aspect fluid path impedance model of the injector system are used. Modeling and adjustment of factors that affect impedance and prevent or reduce backflow, reduce the likelihood of fluid flow rate spikes and provide more accurate flow rates and mixing ratios of fluids may be repeated or happen essentially continuously during an injection. The adjustments may be determined before the injection or determined and/or adjusted during the injection. The determination may include sensor feedback commonly used in injectors such as pressure and position feedback as well as other sensors. In all cases, the user can be notified of adjustments through on-screen notices and/or through the recordation of the injection data by a control device of the injector at the conclusion of the injection.

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 multi-fluid injector system and methods of operation thereof are presented. One embodiment of such a fluid injector system includes an automatic refill procedure for a fluid injector system comprising a fluid injector and an operably engaged syringe. The procedure includes the step of determining, using an electronic control device operably controlling the fluid injector system, whether a fluid injection procedure involving the syringe is impending. If the electronic control device determines that the fluid injection procedure is not impending, such that the automatic refill will not interfere with the fluid injection procedure, an automatic refill of the syringe is initiated.

Abstract: A fluid delivery system and method for determining whether the correct fluid is being drawn into and/or dispensed from a syringe. The system includes a syringe, a fluid injector for drawing fluid into and dispensing fluid from the syringe, one or more sensors adapted to measure a force required to draw the fluid into and/or dispense the fluid from the syringe, a processor in communication with the one or more sensors, and a non-transitory, computer-readable storage medium in operable communication with the processor. The computer-readable storage medium contains one or more programming instructions that, when executed, cause the processor to receive from the one or more sensors one or more measurements of the force required to draw the fluid into and/or dispense the fluid from the syringe and determine from the one or more measurements whether a correct fluid is being drawn into and/or dispensed from the syringe.
