Abstract :
This paper investigates the rotation effect of an axicon ultrasonic transducer when measuring the blood flow rate (Q) in a coronary artery bypass. Results show that, using a system in vitro, for a transducer placed at 90 degrees from the direction of the blood flow, there is not a significant influence in the parameters of the signal due to the effect of rotating the transducer.
