Color Doppler Mode shows flow direction, mean velocities & identifies small vessels not seen in B-Mode

Color Doppler Mode provides a visual overview of flow within the vessel or cardiac structure of interest. Flow direction and velocity can be delineated by red and blue color spectrums and is used for guidance when placing pulsed wave velocity sample volumes. This technique provides rapid identification of vessels, valves of interest and their corresponding flow rates. The ability to quantify flow direction and velocity greatly improves user confidence in vessel identification. Color flow sensitivity can be automatically pre-set by the user for various flow rates such as heart, carotid, kidney or small vessels such as femoral and arcuate arteries.

This option is available for the Vevo 2100 Imaging System.
