A non-invasive central arterial pressure waveform estimation system using ultrasonography for real-time monitoring
… the ABP waveform, conducting simultaneous spectral Doppler and M-mode imaging. The system is characterized in electrical and acoustic domains to preserve adequate signal integrity to faithfully extract a spatial mean flow velocity and an arterial distension waveform. The carotid ABP …

Utilization of Musculoskeletal Sonography in Detecting Physiologic Changes of the Median Nerve in a Working Animal Model
… representation of nerve size. Similarly, the spectral Doppler function possesses the capability of quantifying intraneural microvasculature within the median nerve, by obtaining peak systolic velocities (PSVs) throughout.These methods of using MSK sonography for early detection of symptoms …
