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.
5.4.3 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.The adjusting range is 0-100.
Increasing the gain will brighten the image and you can see more received
signals. However, noise may also be increased.
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.
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.
The function is available in real-time imaging, freeze or cine review status.
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.
There are 6 levels of scan speed available, the smaller the value the faster the
speed.
Speed changing makes it easier to identify disorders in cardiac cycles.
Colorize function provides an imaging process based on color difference rather
than gray distinction.
