5-10 Image Optimization
Impacts
Use phased probe to activate the function in cardiac mode.
Ref. Line
Description
A reference line and a help line meeting the probe icon side 45° display on the 2D
image under GYN and Pelvic Floor exam mode. This helps to locate midsagittal plane
of pelvic floor precisely and define the reference line for measurement.
Operation
Tap [Ref. Line] in the B tab on the touch screen:
Roll the trackball to move the reference line;
Rotate the <Angle> to rotate the reference line around the intersection point.
NOTE: Ref. Lline can be adjusted by pressing <Set> in frozen state.
Impacts
Use intra-cavity probe to activate the function in GYN or Pelvic Floor exam mode.

M Mode Image Optimization
5.3.1
M Mode Exam Operation
1. Select a premium image during B mode scan, and adjust to place the area of interest in the center of
the B mode image.
2. Press <M> on the control panel, and roll the trackball to adjust the sampling line.
3. Press <M> on the control panel again or <Update> to enter M mode, and then you can observe the
tissue motion along with anatomical images of B mode.During the scanning process, you can also
adjust the sampling line accordingly when necessary.
4. Adjust the image parameters to obtain optimized images.
5. Perform other operations (e.g. measurement and calculation) if necessary.
Tips: the M-mark line is displayed for one procedure operation. Press <M> to enter M mode.
5.3.2
M Mode Parameters
In M mode scan, the image parameter area on the right side of the screen displays the real-time
parameter values as follows:
Items
F
D
G
V
DR
Meaning Frequency Depth M Gain M Speed M Dynamic Range
During M mode imaging, menus of image optimizing for B-Mode and M-Mode are displayed on the
touchpad at the same time. You can switch between the 2 modes by tapping the mode tabs.
During M mode scanning, the frequency, depth, and acoustic power of the probe are synchronous
with that of B mode.
Adjustment of the depth or TGC to B Mode image will lead to corresponding changes in M Mode
image.

M Mode Image Optimization
Gain
Description
To adjust the gain of M mode image, the real-time gain value is displayed in the image
parameter area in right corner of the screen.
