Abstract:
1. An injector system for injection of a fluid medium into a patient within an electromagnetic isolation area, the injector system comprising: (a) a powered injector positioned within the isolation area; (b) a first communication unit integral with the powered injector thereby enabling the first communication unit and the powered injector to be moved as a unit; (c) a system controller positioned outside the isolation area, the system controller comprising an operator interface; (d) a second communication unit integral with the system controller; and (e) an intermediate communication unit for ensuring communication between the first and the second communication units and therethrough between the powered injector and the system controller using an authentication technique therewith, the first, the second and the intermediate communication units being adapted to communicate by transmission of radio frequency (RF) energy through the air, the energy being chosen to not create substantial interference with a magnetic resonance imaging scanner.
