Outcome
Accuracy of volumetric flow estimationsurrogate

A novel ultrasonic time-domain correlation method can estimate volumetric blood flow with better than 10% accuracy in idealized experimental models.

Limitations

  • Idealized characteristics used in this study, which include straight circular thin-walled tubes, laminar axially-symmetric steady flow, and no intervening tissues
