Powerhead of a power injection system
First Claim
1. A method of using removable memory in relation to contrast media injector systems, the method comprising:
- manually programming a first injection sequence for a first contrast media injector system comprising a first operator manually providing inputs to the first contrast media injector system and without using the removable memory;
storing the first injection sequence on the first contrast media injector system;
connecting the removable memory to the first contrast media injector system;
downloading the first injection sequence from the first contrast media injector system to the removable memory;
transporting the removable memory to a second contrast media injector system;
connecting the removable memory to the second contrast media injector system;
downloading the first injection sequence from the removable memory to the second contrast media injector system, wherein the first injection sequence is stored on the second contrast media injector system; and
controlling operation of the second contrast media injector system in a programmed manner in accordance with the first injection sequence, wherein the controlling step is executed after the downloading step for the second contrast media injector system.

Abstract
A contrast media injection system includes detects the absolute position of the syringe ram using a non-contact sensor. A series of magnets and Hall-Effect sensors may be used or an opto-reflective system. Illuminated knobs that are connected to the drive mechanism for the syringe ram rotate with the drive and provide visual feedback on operation through the illumination. Analog Hall-Effect sensors are used to determine the presence or absence of magnets that identify the type of faceplate being used. The faceplates include control electronics, connected to the powerhead through connectors, which may be interchangeably used by the two faceplates. The faceplate electronics include detectors for automatically detecting the capacity of pre-filled syringes. Additional features include using historical data to provide optimum pressure limit values during an injection protocol, a removable memory device for storing and transferring information such as injection protocols and injector statistics, and password protection of such protocols.
