Doppler echocardiography - use of Doppler ultrasonography techniques to augment two-dimensional echocardiography by allowing velocities to be registered within the echocardiographic image. Synonym(s): duplex echocardiography
Doppler effect - a change in frequency is observed when the sound and observer are in relative motion away from or toward each other. Synonym(s): Doppler phenomenon; Doppler principle
Doppler flow test
Doppler phenomenon - Synonym(s): Doppler effect

Doppler pulse evaluation
Doppler shift - the magnitude of the frequency change in hertz when sound and observer are in relative motion away from or toward each other.
Doppler ultrasonography - application of the Doppler effect in ultrasound to detect movement of scatterers (usually red blood cells) by the analysis of the change in frequency of the returning echoes.
