Mindray DC-N3S

Image Optimization 5-11
Operation Rotate the <Color> knob clockwise to increase the gain, and anticlockwise
to decrease.
Or adjust it in the image parameter area.
The adjusting range is 0-100.
Impacts Increasing the gain will increase the flow signal presented as well as
noise, while the signals may be missing when the gain is adjusted too low.
ROI Adjustment
Description To adjust the width and position of ROI in Color mode.
Operation When the ROI box is dotted line, roll the trackball to change its size.
When the ROI box is solid line, roll the trackball to change the position.
Press <Set> to switch between the solid line and the dotted line status.
Impacts The larger the ROI box, the lower the frame rate, and the lower the
resolution and color sensitivity.
Frequency
Description Refers to the operating frequency in Color mode of the probe, the real-
time value of which is displayed in the image parameter area in the upper
left corner of the screen.
Operation Select the frequency value through the [Frequency] item in the soft menu.
Or adjust it in the image parameter area.
Values of frequency vary by probes. Select the frequency value according
to the need of the detection depth and the current tissue characteristics.
Effects The higher the frequency, the better the resolution and sensitivity, and the
worse the force of penetration.
B/C Align
Description To set and constrain the maximum width of the B mode image to that of
the Color ROI.
Operation Turn on or off the function through the [B/C Align] item in the soft menu.
Impacts Frame rate will increase when the function is turned on.
Dual Live
Description This function is used to display B image and Color image synchronously.
Operation Click [Dual Live] in the soft menu to turn on or off the function. When the
function is turned on, the window will be automatically switched to the dual
windows (one for B image, and the other for Color image).
Impacts The function is available in real-time imaging, freeze or cine review status.
Steer
Description The feature is used to adjust the ROI of color flow with different angles
with immobility of the linear probe.
