Abstract
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.
Claims2
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
- adjust the at least one characteristic of the injection procedure performed by the fluid injector to ensure that fluid is delivered to a predetermined region of interest in a body of a patient at a particular time such that viable images are produced during an imaging procedure.
