Image Optimization 5-21 
Color Map 
This feature indicates the display effect of Power image. 
The maps in the Power mode image are grouped into two categories: Power maps 
and Directional Power maps. 
To select among the maps, turn the knob under [Color Map] on the touch screen. 
There are 8 kinds of maps provided: P0-3 belong to Power mode maps, while 
Dp0-3 belong to Directional Power mode maps. 
The Power maps provide information of blood flow, which are highly sensitive to 
the low-velocity flows. 
The Directional Power maps provide information of flow direction. 
 
Dynamic Range 
This function is to adjust the transformation of echo intensity into color signal. 
Rotate the knob under the [Dyn Ra.] item on the touch screen to adjust the 
dynamic range. 
Increasing dynamic range will lead to higher sensitivity to low-power signals, thus 
enhances the range of signals to display.
