Fig. 5From: Optimization of beam-flow angles for Doppler ultrasound flow velocity measurements using slanted gel padsScatter plot with line fit of flow velocity and angle shows a significant linear correlation (P = 0.000, R2 = 0.491) between beam-flow angle and PSV, with PSV overestimation progressively increased as beam-flow angles increased even with Doppler angle correctionBack to article page
