A system and method for tracking an anatomical structure over time based on Pulsed-Wave (PW) Doppler signals of a Multi-Gated Doppler (MGD) signal is provided. The method may include identifying a gate corresponding with a selected anatomical structure. The method may include analyzing an MGD signal to track the selected anatomical structure over an extended period of time by selecting, at a plurality of sample times during the extended period of time, a PW Doppler signal from a plurality of PW Doppler signals of the MGD signal. Each of the selected PW Doppler corresponds with the selected anatomical structure at the particular sample time. The method may include presenting a continuous PW Doppler signal generated from each of the PW Doppler signals selected at each of the sample times during the extended period of time at a display system.
