Point of Care OB/GYN Ultrasound Physics: Module 6: Introduction to PW Spectral Doppler

Building on the concepts taught in the previous module, Module 6 develops an understanding of the specifics of Pulsed Wave (PW) spectral Doppler. The module begins with an illustration of the information contained in a Doppler spectrum. From here, you will learn how PW Doppler is performed, the importance of the PW Doppler sample volume, and the angle dependence of the spectral Doppler. Once you have learned the fundamentals of PW spectral Doppler, the module reviews the Doppler system controls related to spectral brightness and signal strength, velocity display, low velocity flow, sweep speed, and auto spectral optimization. As with the system controls module, the controls will be taught through direct application on actual Doppler spectrums. Finally, the module reviews spectral characteristics, measurements, and indices. We explore the effects of resistance on spectral Doppler waveform characteristics as are needed for assessments of the umbilical artery.
