Q2-) You are measuring blood velocity V at the aorta using doppler ultrasound. The angle 0=60°, Transmitter frequency ft=10Mhz. Sound velocity in blood, c = 1579m/s. Doppler shift fa is measured as 19kHz. а) b) the cross sectional area of the aorta for the given parameters? 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 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
