Abstract
Injector systems including a syringe for use with a powered injector having a drive membre to inject a fluid into a patient having a first indicator positioned on the syringe at a predetermined position are described. The position of the first indicator may be associated with information about the syringe configuration. The first indicator can, for example, be positioned on a rear surface of an attachment flange of the syringe. The injector system includes sensors each having on and off states, and a shutter mechanism configured to place sensors in the on or off states. The state of each of the sensors provides a digital code corresponding to information on the syringe configuration.
