Abstract :
An inexpensive sample volume (SV) tracking unit has been developed for use in pulsed Doppler echocardiography (PDE). The tracking unit allows the SV depth to be modulated by any desired time-varying function. Consequently, artifacts created by wall and leaf-let motion are minimized in the Doppler audio signal.
