System and Method for Syringe Fluid Fill Verification and Image Recognition of Power Injector System Features

摘要

A fluid injection system and a fluid verification system for confirming that a syringe, containing a fluid for injection, is fully filled with fluid and neither has free space (i.e., air) near the distal end thereof when the syringe is provided in an upright position nor contains air bubbles. Imaging processing techniques and systems are also provided to determine various injection parameters and to verify the type and certain properties of fluid that is present within a syringe.

1. A syringe comprising:
a syringe barrel comprising a proximal end and a distal end comprising an angled surface; and a plunger slideably disposed in the syringe barrel and configured to advance through the barrel to expel a fluid therefrom, wherein the plunger comprises a transparent or translucent material configured to transmit electromagnetic radiation therethrough such that an illuminated identification pattern is formed at a predetermined portion of the distal end of the syringe barrel when the syringe is filled with the fluid.
