A method and system determine, with a computer system including one or more processors, a plurality of parameters associated with a volume in an object over time in a series of sequence blocks. In a sequence block in the series of sequence blocks, the plurality of parameters are determined as occurring simultaneously in the volume in the object. At least one parameter of the plurality of parameters varies from the sequence block to another sequence block in the series of sequence blocks, and the plurality of parameters include a contrast related parameter associated with a concentration of a contrast agent in the volume in the object over time in the series of sequence blocks. The computer system generates a signal evolution based on the plurality of parameters of the volume in the object over time in the series of sequence blocks, the signal evolution defining the contrast related parameter over time in the series of sequence blocks.

A system and method for promoting and safeguarding the wellbeing of patients in relation to a fluid injection may obtain patient data; determine, based on the patient data, an initial risk prediction for a patient for a fluid injection to be administered to the patient, the initial risk prediction including a probability that the patient experiences at least one adverse event in response to the fluid injection; provide, to a user device, before the fluid injection is administered to the patient, the initial risk prediction; determine, after the fluid injection is started, sensor data associated with the patient; determine, based on the sensor data determined after the fluid injection is started, a current risk prediction including a probability that the patient experiences the at least one adverse event in response to the fluid injection; and provide, to the user device, the current risk prediction.

System, device and method for safeguarding the wellbeing of patients for fluid injection

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.

Provided is a method for delivering a medical fluid. The method includes delivering a fluid volume, which includes contrast and/or a flush fluid, at a preselected total volumetric flowrate during a first duration of a fluid delivery procedure. The amount of the contrast agent and the flush fluid in the fluid volume can be controllably varied during the first duration of the fluid delivery procedure so as to substantially maintain a preselected total volumetric flowrate throughout the first duration of the fluid delivery procedure. Also provided is a fluid delivery system capable of performing this method.

System and method for delivering a fluid with a consistent total volumetric flowrate

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.

System and method for improved fluid delivery in multi-fluid injector systems

Systems and methods for intelligently delivering fluid to a targeted tissue are described. The systems and methods may include directing a pump to distribute fluid to a targeted tissue and receiving one or more signals from an intracorporeal sensing system, where the one or more signals correspond to one or more sensed feedback parameters at the targeted tissue. The systems and methods may also include determining whether the one or more sensed feedback parameters are within an acceptable range. If the one or more sensed feedback parameters are not within the acceptable range, the systems and methods may include determining an adjusted velocity for the plunger necessary to adjust the pressure of the fluid in the pump so that the one or more sensed feedback parameters move within the acceptable range and directing the pump to distribute the fluid at the adjusted velocity.

Medical fluid injector

A diagnostic contrast composition includes a carrier fluid and a non-decaying gas-evolving fluid incorporated in the carrier fluid. The gas-evolving fluid has a vapor pressure sufficient to evolve the gas from a circulatory system within a lung of a patient. The gas-evolving fluid is a composition containing a sufficient quantity of atoms with an atomic number higher than 8 to provide an increased absorption sufficient to increase a Hounsfield Unit measurement in an image in a CT imaging system. The gas-evolving fluid is selected from the group consisting of xenon gas, krypton gas, sulfur hexafluoride, a perfluorocarbon, a brominated perfluorocarbon, and combinations thereof. The carrier fluid is selected from the group consisting of water, saline, saline comprising one or more blood proteins, and saline comprising dissolved lipids.

At least one engagement member protrudes from a terminal portion of the sidewall in a proximal direction along the longitudinal axis. The at least one engagement member tapers axially in a direction from the distal end toward the proximal end. The at least one engagement member is configured for engagement with a locking mechanism of a fluid injector to releasably lock the syringe with the fluid injector. A taper of the at least one engagement member is configured to rotationally guide the syringe into alignment with the locking mechanism and axially eject the syringe upon rotation of the syringe. The locking mechanism operatively engages the at least one engagement member regardless of an orientation of the syringe about the longitudinal axis relative to the injector.
