Find blood velocity V.
Typical cardiac output from left ventricle to aorta is about 4.8L/min. What is
transducer
(frequency f)
Doppler frequency (f d) = 2. ft. V. cos e
beam
fd - doppler shift
C - is speed of sound in tissue
ft - transmited beam
V - velocity of the blood
0- angle of incidence between the ultrasound
beam and the direction of the flow
flow velocity = V
