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.
