Abstract
An injector system for injection of a fluid medium into a patient within an electromagnetic isolation area. The injector system includes a powered injector, a system controller therefor, and a plurality of communication units. The powered injector is positioned within the isolation area. A first communication unit integral with the powered injector enables the first communication unit and the powered injector to be moved as a unit. The system controller is positioned outside the isolation area and has a second communication unit integral therewith. An intermediate communication unit ensures 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, second and intermediate communication units are adapted to communicate by transmission of radio frequency (RF) energy. The RF energy is chosen to avoid interfering with the operation of MRI scanners.
