5-30 Image Optimization 
SV 
Description
To adjust the SV position and size of sampling in PW mode, the real-time 
value of SV and SVD are displayed in the image parameter area in the 
upper left corner of the screen. 
Operation  Adjust the SV size through the [SV] item in the soft menu or menu. 
Roll the trackball to adjust the SV depth. 
Or adjust the SV directly in the image parameter area. 
The adjusting range is 0.5-20.0mm. 
Effects  The smaller the SV size, the more accurate the result; and more 
information can be obtained when selected large SV size. 
 
5.8  Anatomical M Mode 
CAUTION:
Anatomical M images and Color Anatomical M images are 
provided for reference only, not for confirming a diagnosis. 
Please compare the image with that of other machines, or make 
diagnosis using none-ultrasound methods. 
5.8.1  Free Xros M Mode 
For an image in the traditional M mode, the M-mark line goes along the beams transmitted 
from the probe. Thus it is difficult to obtain a good plane for difficult-to-image patients that 
cannot be moved easily. However, in the anatomical M mode, you can manipulate the 
M-mark line to move to any position at desired angles. The system supports anatomical M 
scanning (including Free Xros M mode and Free Xros CM mode) in 2D imaging modes (B, 
Color, Power and TVI mode).

  Shortcut key for Free Xros M mode 
Assign a user-defined shortcut key for Free Xros M: [Setup] → [System Preset] → [Key 
Config]. Please refer to "15.1.7 Key Config" for details. 
  Real-time Imaging 
1.  In real-time B mode or M mode, adjust the probe and image to obtain the desired 
plane. 
2.  Click [Free Xros M] in the soft menu or menu to enter Free Xros M mode, or press the 
user-defined key. 
3.  Adjust the M-mark (single or multiple) line to obtain optimized images and necessary 
information. 
In Dual-split or Quad-split mode, it is the current activated window that enters the 
Free Xros M Mode. 
  Imaging in Freeze Mode 
1.  Free Xros M imaging of images in cine memory 
 
For B frozen images, press <M> or click [Free Xros M] in the soft menu, or press 
the user-defined key directly.
