Abstract:
1. A method for performing a filling sequence in a contrast media injector system that uses a fill tube coupling a syringe to contrast media supply to fill the syringe with a desired fill volume of contrast media, the method comprising: attaching said fill tube to said syringe; drawing contrast media into the syringe through the fill tube at a first fill rate; thereafter, automatically expelling substantially all air from the fill tube by automatically reversing the first fill rate and expelling fluid from said syringe, wherein at least some of the contrast media is expelled through the fill tube during the expelling; thereafter, filling the syringe at a second fill rate to fill the syringe with the desired fill volume of contrast media, wherein the second fill rate is faster than the first fill rate; and thereafter, injecting contrast media into a patient.
