• Doppler ultrasound employs the doppler effect to determine whether blood flow is towards or away from the probe and its relative velocity. Calculated by the frequency shift of a particular sample volume. Doppler shift falls in the audible range - the machine uses stereo speakers to produce a pulsating sound.
• Doppler ultrasound - colour map of flow is usually

  • red towards the probe
  • blue away from the probe
