Image Optimization 5-13
5.4.3 Color Mode Image Optimization
Color Gain
Description Refers to the overall sensitivity to flow signals. This function is used to adjust the
gain in Color 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.
ROI Adjustment
Description This function adjusts the width and position of the ROI in Color mode.
Operations Tap the corner (green dot) of the ROI and drag to change the size.
Tap inside the ROI box and drag to change the position.
Impacts The larger the ROI box, the lower the frame rate, and the lower the resolution
and color sensitivity.
Frequency (Image Quality)
Description Refers to the operating frequency of the probe in Color mode, the real-time value
of which is displayed in the image parameter area in the top-left corner of the
screen.
Operations
Select the different frequency values through at the left part of the image
area.
The adjusting range of frequency values can be divided into 3 levels: penetration
preferred (Pen), general mode (Gen), and resolution preferred (Res).
Frequency values vary according to probe types. Select the frequency according
to the needs of the detection depth and the current tissue characteristics.
B/C Align
Description To set and restrict the maximum width of the B mode image to that of the Color
ROI.
Operations Turn the function on or off using the [B/C Align] control.
Impacts The frame rate increases when the function is turned on.
Steer
Description The feature is used to adjust the ROI of the color flow of different angles with
immobility of the linear probe.
Operations Steer the probe by tapping buttons on the bottom of the image area.
