Estimating the term…
A front-loading syringe which comprises a movable plunger for injecting liquid contrast media, is rotatably mountable on a front wall of an injector housing with an interference fit and in sealed relationship with respect thereto, with or without a pressure jacket, by a first-quick release mechanism. At the same time, the plunger is connected to an injector drive mechanism by a second readily releasable mechanism. During the mounting operation, a sensor reads injection information from an indicator device on the syringe and feeds it to an injector control. An audible-and-tactile indicating mechanism also is activated when the syringe is essentially in the desired mounted position. The syringe may include reinforcing ribs which also function as volumetric gradations, and liquid media presence-or-absence indicating dots which appear circular against a liquid media background and oval-shaped against an air background. An injection end of the syringe comprises an injector portion of reduced diameter inside a screw-threaded attachment portion of larger diameter, and may include loop-shaped reinforcing handle portions.

A method of providing syringe information to an injector, comprising:
An encoding device for use with an injector comprising a motor operable to drive a piston, a housing comprising at least one retaining flange, a sensor associated with the housing and a control unit in communication with the sensor and the motor, the encoding device providing syringe information and operable to engage the at least one retaining flange on the housing, the sensor operable to read the syringe information provided by the encoding device as the encoding device is rotated to cause engagement with the at least one retaining flange and to forward the syringe information to the control unit, the control unit operable to receive the syringe information from the sensor and to control the motor of the injector based on the syringe information.
