The "HD-Flow Main" menu has to be active.
Select the [HD-Flow Sub] key. The HD-Flow Submenu appears.
Changes are only possible in scan mode. Changes in the HDF Map, Balance, Scale and
Threshold are also possible in freeze mode.
This function allows selection of the color coding for an optimization of the display 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:
