1. A power injector comprising:
- a syringe plunger driver comprising a motorized drive source;
a syringe comprising a syringe plunger, wherein said syringe plunger driver interacts with said syringe plunger to move said syringe plunger within said syringe in at least in a first direction;
power injector control logic comprising an injection protocol, wherein said injection protocol comprises a flow rate decay constant, and wherein execution of said injection protocol by said power injector, using said power injector control logic, generates an exponentially decaying flow rate injection;
data storage accessible by said power injector control logic and comprising a plurality of data entries, wherein each data entry of said plurality of data entries comprises a flow rate decay constant value and an imaging device identifier, wherein a first data entry of said plurality of data entries comprises a first flow rate decay constant value and a first imaging device model, wherein a second data entry of said plurality of data entries comprises a second flow rate decay constant value and a second imaging device model, wherein said first flow rate decay constant value is different from said second flow rate decay constant value, wherein said first imaging device model is different from said second imaging device model, wherein said first flow rate decay constant value is used by said power injector to execute said injection protocol for a first imaging operation that uses power injector and said first imaging device model, and wherein said second flow rate decay constant value is used by said power injector to execute said injection protocol for a second imaging operation that uses said power injector and said second imaging device model; and
a user input device operable to identify one of said data entries from said plurality of data entries as a selected data entry, and wherein said flow rate decay constant value of said selected data entry is used as said flow rate decay constant for execution of said injection protocol by said power injector using said power injector control logic.

Abstract
A power injector is disclosed having power injector control logic, which in turn includes a decay constant cross-reference, for instance in the form of a data structure. Flow rate decay constant information may be stored by the decay constant cross-reference. A decay constant, which may be used by the power injector to generate an exponentially decaying flow rate for an injection, may be stored in the decay constant cross-reference in conjunction with a particular imaging unit. The decay constant cross-reference may be searched by entering a model or module number of an imaging unit to identify the corresponding flow rate decay constant to be used by the power injector.
