This function allows selection of the color coding for an optimized view of blood flow (similar to
the post-processing curves with gray scale 2D-scans). It is useful especially with low flow
rates. It may be altered in real-time or Freeze-Mode, respectively.
The color is coded in a color wedge:
PD Map1 PD Map 2
cyclamen gray-green

yellow light yellow
PD Map 5 PD Map 6

light yellow yellow
Strong echo: lighter hue (high brightness) Weak echo: darker hue (low brightness)
Selection of a PD Map curve:
Select the [PD Map] key and select the PD Map curve by selecting 1 to 8.
If desired, activate Gently Color. 'Gently Colors' on page 8-37
Triplex mode is the simultaneous real-time display of 2D mode, Power-Doppler and Spectral
Doppler.
There are one possibility to combine Power-Doppler (PD) with Spectral Doppler Information:
1. PD + 2D Mode + PW Doppler (Pulsed Wave Doppler)
In scan mode it is possible to switch between PD menu, PW menu and the appendant
Submenus to readjust the settings.
2. PD + 2D Mode + CW Doppler (Continuous Wave Doppler)
