Point of Care MSK Ultrasound Physics: Module 6: PW Spectral Doppler

Building on the concepts taught in the previous module, this module develops an understanding of the specifics of Pulsed Wave (PW) spectral Doppler. Because of the limited role of PW in MSK, this module focuses on the basics required to make sure that a PW spectrum can be obtained. 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, and sweep speed. As with the system controls module, the controls will be taught through direct application on actual Doppler spectrums. Finally, the module concludes with examples of the application of pulsed wave Doppler in Musculoskeletal Ultrasound.
