8.3.3.1 CF Map and Display Mode
This function allows selection of the color-coding for the blood flow display (similar to the post-
processing curves with gray scale 2D). It is useful especially with low flow rates. It may be
altered in real time or Freeze mode, respectively.
Velocity display (Display V), velocity-turbulence display (Display V-T) and velocity-power
display (Display V-Pow) each have different color pattern maps available for selection.
Selection of a CF Map curve:
Select [CF Map] key and select the desired CF Map curve by selecting key 1 to 8.
Note
If desired activate Gently Colors.

8.3.4 CF + 2D + Spectral Doppler (Triplex Mode)
Triplex mode is the simultaneous real time display of 2D mode, Color Doppler and Spectral
Doppler.
There are one possibility to combine Color Flow(CF) with Spectral Doppler Information:
1. CF + 2D + PW Doppler (Pulsed Wave Doppler)
In scan mode it is possible to switch between CF menu, PW menu and the appendant
Submenus to readjust settings.
Note
The color box position is not changing when activating the PW mode!
2. CF + 2D Mode + CW Doppler (Continuous Wave Doppler)
In scan mode it is possible to switch between CFM menu, CW menu and the Submenus to
readjust settings.
8.4 Power Doppler Mode (PD Mode)
Sonographic diagnostics can be greatly extended by Color-Doppler sonography. Still, Color-
Doppler sonography has deficits, especially when displaying very slow flow velocities - like
neovascularization found in malign tumors. The Power Doppler intends to erase this deficit by
displaying such slow flow velocities. In gynecologic and obstetric applications the advantages
can be clearly seen in the display of placenta blood circulation. With eutrophic fetus the blood
flow can be seen over the total width of the placenta. In the radiology field too, advantages
