Abstract

A system and method of managing workflow for a variety of injection procedures preferably includes a display that provides a graphical representation of the steps required to initiate an injection procedure. The system can, for example, set forth a suggested order or sequence for the steps to be completed, and display the suggested sequence of steps graphically. Various steps may optionally require completion of ancillary operations as a requirement for completion of the selected step.

Claims

1. A fluid injection apparatus comprising:

(a) at least one pressurizing mechanism for use with a first fluid container for pressurizing a first fluid therein for injection into a patient, the first fluid comprising a contrast enhancing agent;

(b) a controller operably associated with the at least one pressurizing mechanism, the controller comprising a programming system to allow programming of an injection protocol comprising parameters for at least one phase of the injection protocol;

(c) a user interface system comprising an input mechanism via which an operator can input a desired output contrast time enhancement curve, the user interface system further comprising a display; and

(d) a first model to determine the injection protocol to achieve the desired output contrast time enhancement curve input by the operator; and

(e) a second model to provide a calculated output contrast time enhancement curve if the operator inputs at least a portion of the injection protocol, wherein the operator may choose at least one of the first model and the second model via the user interface system, and wherein the calculated output contrast time enhancement curve is displayed on the display if the operator chooses the second model and the determined injection protocol is displayed on the display if the operator chooses the first model.
