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.
