How is the tip of the syringe positioned in the turret?

The correct choice focuses on how the flange of the syringe is designed to fit precisely into a notch on the turret. This design ensures that the syringe is securely held in place, allowing for accurate administration of contrast media or other substances during interventional procedures. The notch aligns the syringe in the proper orientation, which is vital for both safety and efficacy during operations.

This design feature not only helps maintain stability but also ensures that the syringe can be easily removed and replaced when needed without compromising the overall functionality of the injector. This is particularly important in a clinical setting where efficiency and precision are crucial for patient outcomes.
