TD Mode
10.3.4 Baseline
The TD baseline shift can be used to prevent aliasing in one flow direction similar to the Doppler
baseline shift. Shifting the TD baseline enlarges the velocity range in one direction.
The zero line of the color bar is also shifted.
Adjust the zero line +/-
There are
8 steps in each direction.
By step 8 you see only the color wedge in one direction (maximum velocity).
The other direction is 0 (kHz, cm/s, m/s).
The maximum value and minimum value of the flow velocities are displayed at the upper and lower
edge of the color wedge.
10.3.5 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 TD Ensemble the frame rate decreases.
Remarks:
*
Changes are only possible in write mode!
