For a few presets, there is a control available in the color flow mode for alternating between high and low velocity scales. A higher velocity scale is needed to avoid aliasing while imaging of faster (arterial) flow. A lower velocity scale optimizes the imaging of slow flow (venous).
The presets that support selection between high and low velocity scale are following:
Curved Array | Linear Array |
Abdominal | Vascular |
OB-Gyn | MSK |
Vascular | Small Parts |
Cardiac |
To change the velocity scale, tap on the

indicating the lower scale. The velocity setting corresponding to both scales can be seen at the top of the velocity bar
