Adjusting the flow velocity range
To adjust the flow velocity range, use the [Scale]
knob.
NOTE: Decreasing the scale control may allow more low-velocity signals from moving
tissues to be introduced, thereby potentially lowering the Color Doppler
velocities displayed on the screen.
Note that, depending on the flow dynamics and the surrounding tissues, it may
be necessary to raise the scale control to optimize the Color Doppler display.
