5-10 Image Optimization
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;

NOTE: Ref. Lline can be adjusted by pressing <Set> in frozen state.
Use intra-cavity probe to activate the function in GYN or Pelvic Floor exam mode.
5.3 M Mode Image Optimization
5.3.1 Basic Procedures for M Mode Imaging
1. Select a high-quality image during B mode scanning, and adjust to position 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. You can then observe the
tissue motion along with the 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.
If “Sampling Line Displaying” is selected, then the screen will display the sampling line all the time and
pressing <M> one will lead to entering M mode directly. See “5.1.3 Quickly Saving Image Settings”
chapter for details.
5.3.2 M Mode Image Parameters
In M mode scanning, the image parameter area in the top-right corner of the screen displays the
real-time parameter values as follows:
Parameter F D G V DR
Meaning Frequency Depth M Gain M Speed M Dynamic Range
During M mode imaging, menus for B mode and M mode are displayed on the touch screen at the
same time. You can switch between the 2 modes by clicking the mode tabs.
During M mode scanning, the frequency, depth, focus position and acoustic power of the probe are
synchronous with that of B mode.
Adjustment of the depth, focus position or TGC to the B mode image will lead to synchronous
changes in the M mode image.
