1. An encoded element for use with a syringe and an injector in communication with a detector comprising a plurality of electrically conductive readout contact members, the encoded element comprising:
- an attachment mechanism adapted to detachably connect the encoded element to a plunger of the syringe or a drive member of the injector; and
a storage system comprising a plurality of electrically conductive code contact members, the storage system being operable to store encoded syringe information readable by the detector when the syringe is engaged with the injector and to convey the syringe information to the detector when contact is made between the storage system and the detector.

Abstract
Apparatuses for sharing information on syringe configuration between syringes and injector systems comprise a storage system to store encoded information on syringe configuration. The encoded information is readable by a detection circuit in an injector. In one embodiment, the storage system is an electronic storage system in which information relevant to the syringe configuration is encoded. A method comprises the step of conveying syringe configuration information to a detector in an injector for use with the syringe.
