Baseline

The CFM baseline shift can be used to prevent aliasing in one flow direction similar to the PW
Doppler baseline shift. Shifting the CFM baseline enlarges the velocity range in one direction.
The zero line of the color bar is also shifted.
There are
By step 8 you see only the color wedge in one direction (maximum velocity), the other
direction is 0 (kHz, cm/s , m/s).
Only possible in Display Mode V, V-T and V-Pow
The maximum value and minimum value of the flow velocities are displayed at the upper and lower
edge of the color wedge.
8.3.7

Ensemble

This function controls the number of pulses for one displayed Color-Doppler line. Since several pulses
are to be evaluated for display of a result, the color display quality increases with the number of
evaluated pulses.
Switch the [Ensemble] key and select the number of pulses per color line.
max. value: 31
min. value: 7
step size: 1
Switch up or down to increase or decrease the number of pulses per color line.
With increasing CFM Ensemble the frame rate decreases.
Remark: Changes are only possible in write mode!
8.3.8

Line Density

This function determines the line density within the CFM box. The lower the line density, the greater
the distance between lines and the size of the color pixels.
Switch the [Line D.] key and adjust the line density.
Switch up or down to increase or decrease the line density.
max. value: 9
min. value: 1
step size: 1
Remark: Changes are only possible in write mode.
