Doppler ultrasound methods Task: 1. Using the colour flow imaging display the flow in the tube of inner diameter 8 mm. 2. Using spectral Doppler flow measurements measure the maximum and average velocity in tubes of inner diameter 8 and 4 mm. Calculate the volume flow in these tubes. 3. Compare the character of velocity spectrum and maximum and average velocities in prestenotic and poststenotic region.
