Color Aliasing
If the blood flow velocity exceeds the maximum velocity range
the system can cover, based on the sampling rate used, aliasing
occurs.
Aliasing appears as a shift in color from the color representing
positive velocity to color representing negative velocity or visa
versa.
The maximum velocity is displayed on top of the color bar.
Color steer
Slant the ROI (Region of Interest) of the Color Flow linear image
left or right to get more information without moving the probe.
Press and hold the color region of interest. The region of interest
changes to yellow, indicating it is ready to be steered in a
different direction. Drag the region of interest to the left or right
depending on the desired angle.
NOTE: Angle Steer applies only to the linear functionality of the Dual
Probe.
