Denne protokol viser, hvordan man anvender ultrahurtig ultralyd Doppler billeddannelse til at kvantificere blodstrømme. Efter en 1 s lang erhvervelse, har eksperimentator adgang til en film af det fulde synsfelt med aksial hastighed værdier for hver pixel hver ≈0,3 ms (afhængigt af ultralyd tidspunkt for flyvningen).
