WebDetection of Damaging Winds. Doppler radar velocity data can show areas of diverging winds at the surface, and even the strength of those winds, indicating a downburst. Winds coming together at midlevels of the storm, known as convergence, can also be seen on velocity displays and can indicate the development of a downburst. WebColor Doppler can be used to assess the vascularity of an ovarian mass. Color Doppler, although sensitive to high-velocity flow, is less effective in depicting low-velocity flow. …
WebLow velocity blood flow occurs mainly in small veins, venules, and capillaries. The minimum detectable flow velocity is inversely dependent on the ultrasound frequency; when using a 2.5 MHz probe, the minimum detectable flow velocity is 1.5 cm/s. In addition, commercial Doppler devices are typically limited to the frequency below 15 MHz; the ...
