5-22 Image Optimization 
5.10  Anatomical M Mode (Free Xros M) 
CAUTION: 
Anatomical M Mode and Color Anatomical M mode 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. 
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) in 2D imaging modes (B, Color, Power and TVI mode). 
  Shortcut key setting 
You can preset a user-defined key for entering Free Xros M mode: [Setup] -> [System 
Preset] -> [Key Config], Refer to “12.1.6 Key Config” for details. 
 
  Free Xros M Imaging Procedures 
1.  In real-time 2D mode or M mode, adjust the probe and image to obtain the desired plane. 
Or select the desired 2D cine files. 
2.  Click [Free Xros M] on the image menu of the B mode to enter Free Xros M mode, or 
press the user-defined key. 
3.  Adjust the M-mark line to obtain optimized images and necessary information.

Xros M mode. 
Free Xros M imaging is supported on frozen B image, B+M image and B+Power/Color/TVI 
image.
