Encoding and sensing of syringe information
First Claim
1. An injector for use with an encoded syringe or an encoded syringe adapter, the injector comprising:
- an interface adapted to attach the syringe or the syringe adapter to the injector;
a positioning subassembly comprising a translucent surface through which light can pass; and
at least one abutment member spaced from the translucent surface to position the encoded syringe or the encoded syringe adapter seated in a gap formed between the translucent surface and the abutment member at a desired position relative to the translucent surface,at least one energy source disposed axially rearward of the positioning subassembly and adapted to direct energy in an axial direction; and
at least one sensor adapted to detect energy impinging thereupon as a result of the encoding of the syringe or the syringe adapter;
wherein the at least one energy source comprises a light source.

Abstract
A syringe for use with a powered injector to inject a fluid into a patient inclides an encoder. The encoder includes at least a first indicator positioned on the encoder. The first indicator is adapted to interact with at least a portion of energy being propagated through or adjacent the encoder in a manner that is detectable. The presence (or absence) of the first indicator provides or corresponds to information about the syringe configuration. The indicator(s) of the present invention can, for example, provide information about syringe configuration by the number and/or position thereof. A plurality or set of such syringes can be provided, with the configuration of each such syringe being represented by the presence or absence of indicator(s) of that syringe.
