Questo protocollo mostra come applicare l'imaging Doppler ad ultrasuoni ultraveloce per quantificare i flussi sanguigni. Dopo un'acquisizione lunga 1 s, lo sperimentatore ha accesso a un filmato dell'intero campo visivo con valori di velocità assiale per ogni pixel ogni ≈0,3 ms (a seconda del tempo di volo ad ultrasuoni).
