Ce protocole montre comment appliquer l’imagerie doppler ultrason ultra-pur pour quantifier les flux sanguins. Après une longue acquisition de 1 s, l’expérimentateur a accès à un film de plein champ de vision avec des valeurs de vitesse axiaale pour chaque pixel chaque ≈0,3 ms (selon l’heure d’échographie du vol).
