Abstract

Claims (10)

1 . A fluid injection system comprising:

a fluid injector;

a syringe operatively engaged with the fluid injector;

an image capture device positioned to capture an image of at least a portion of a barrel of the syringe; and

at least one computing device in communication with the fluid injector and the image capture device, the at least one computing device comprising at least one processor configured to:

obtain the image of at least the portion of the barrel of the syringe;

determine, based on the image of at least the portion of the barrel of the syringe, an outside diameter of the syringe along a length of the barrel of the syringe;

determine, based on the outside diameter of the syringe along the length of the barrel of the syringe, at least one characteristic of an injection procedure performed by the fluid injector; and
