5.3.2 M Mode Parameters
In M mode scan, the image parameter area on the left 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
touch screen 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.
5.3.3 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 left corner of the screen.
Operation Rotate <M> knob clockwise to increase the gain, and anticlockwise to decrease.
Effects Increasing the gain will brighten the image and you can see more received signals.
However, noise may also be increased.

Effects
Adjust according to the actual situation and obtain a desired analysis through
comparison.
Speed
Description
This function is used to set the scan speed of M mode imaging, and the real-time
speed value is displayed in the image parameter area in the left corner of the screen.
Operation
Turn the knob under [Speed] on the touch screen to complete the adjustment.
The smaller the value is, the slower the speed becomes.
Effects
Speed changing makes it easier to identify disorders in cardiac cycles,
