PD Mode
9.3.4 Ensemble
This function controls the number of pulses for one displayed Power-Doppler line. Since several
pulses are to be evaluated for displaying 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 to increase or down to decrease the number of pulses per color line.
With increasing PD Ensemble the frame rate decreases.
Remark:
Changes are only possible in write mode!
9.3.5 Line Density
This function determines the line density of the Power-Doppler box. The lower the line density, the
greater the distance between lines and the size of the color pixel.
Switch the [Line D.] key and adjust the line density.
max. value: 9
min. value: 1
step size: 1
Switch up to increase or down to decrease the line density.
Remark: Changes are only possible in write mode!
9.3.6 PD-Map
This function provides selectability of the color coding for an optimization of the display of blood
flow (similar to the post-processing curves with grayscale 2D). It is useful especially with low flow
rates. it may be altered in real time or Freeze mode, respectively.
Switch the [PD Map] key repeatedly to select the PD Map curve. (1 to 8)
The Power is the amplitude of Doppler echoes , displayed as brightness in the image.
