5-8 Image Optimization 
  During M mode imaging, you can switch between B and M menu from the menu title. 
  During M Mode scanning, frequency and acoustic power of the transducer are 
synchronous with that of B Mode. 
  Adjustment of the depth or TGC to the B Mode image will lead to corresponding changes 
in M Mode image. 
5.5.3  M Mode Image Optimization 
Gain 
To adjust the gain of M mode image. The real-time gain value is displayed in the 
image parameter area in the upper left corner of the screen. 
Rotate the <Gain/ iTouch> knob clockwise to increase the gain, and anti-
clockwise to decrease. 
Increasing the gain will brighten the image and you can see more received 
signals. However, noise may also be increased. 
Focus Position 
To change the focus position in M mode, symbols as " " of which are displayed 
on the right of the image. 
Adjust the focus position through the [Focus Position] item in the menu. 
Display Format 
To set the display format of M mode image with B mode image. 
Adjust through the [Display Format] item in the menu; 
There are 4 formats available for the images display: V1:1, V1:2, V2:1, Full. 
Adjust according to the actual situation and obtain a desired analysis through 
comparison. 
Speed 
This function is used to set the scanning speed of M mode imaging, and the 
real-time speed value is displayed in the image parameter area in the upper 
left corner of the screen. 
Change the speed through the [Speed] item in the menu; 
The smaller the value the faster the speed. 
Effects 
Speed changing makes it easier to identify disorders in cardiac cycles. 
Colorize and Colorize Map 
Colorize function provides an imaging process based on color difference rather 
than gray distinction. 
Turn on or off the function through the [Colorize] item in the menu; 
Select the colorize map through the [Colorize Map] item in the menu; 
Impacts 
The function is available in real-time imaging, freeze or cine review status. 
Gray Map 
Adjusting grayscale contras to optimize the image.
