5-18 Image Optimization
5.5.3 Power Mode Image Optimization
Power Gain
Description Refers to the overall sensitivity to flow signals. This function is used to adjust the
gain in Power mode.
The real-time gain value is displayed in the image parameter area in the top-left
corner of the screen.
Operations Drag the [Gain] control on the right part of the image area to adjust the gain.
Effects Increasing the gain will increase the flow signal presented and noise. The
signals may be missing when the gain is adjusted too low.
Power Map
Description This feature indicates the display effect of the Power image.
Maps in the Power mode image are grouped into two categories: Power maps
and Directional Power maps.
Operations Select maps by using [Color Map] control.
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 about blood flow, which are highly
sensitive to the low-velocity flows.
The Directional Power maps provide information about flow direction.
Dynamic Range
Description This function adjusts the transformation of echo intensity into color signal.
Operations Adjust dynamic range through [Dyn Ra.].
Tap [-] or [+] to change the value slightly or drag the control directly.
The adjusting range is 10-70 in increments of 5.
Effects Increasing the dynamic range leads to higher sensitivity to low-power signals,
thus enhancing the range of signals to display.
