– Current image;
– Analysis curve data;
– Analysis parameter.
7. Press the user-defined key for “TDI QA” to exit the quantitative analysis.
6.5 M Mode
6.5.1 M Mode Image Scanning
Perform the following procedure:
1.
Select a premium image during B mode or B+ Color scan, and adjust to place the area of
interest in the center of the image.
2. Press <M> on the control panel, and use the trackball/trackpad to adjust the sampling line.
3. Press <M> on the control panel again or <Update> to enter M mode, and then you can observe
the tissue motion along with anatomical images of B mode. During the scanning process, you
can also adjust the sampling line accordingly when necessary.
4. Adjust the image parameters to obtain optimized images.
6.5.2 M Mode Image Parameters
Gain
To adjust the gain of M mode image, the real-time gain value is displayed in the image parameter
area.
Increasing the gain will brighten the image and you can see more received signals. However, noise
may also be increased.
Display Format
To set the display format of B mode image and M mode image.
Adjust according to the actual situation and obtain a desired analysis through comparison.
Speed
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.
Tint Map
This function provides an imaging process based on color difference rather than gray distinction.
Gray Map
Adjusting grayscale contrast to optimize the image.
Edge Enhance
This function is used to increase image profile, so as to distinguish the image boundary.
Larger edge enhance may lead to noise increase.
Dynamic Range
Adjusts contrast resolution of an image, compresses or expands gray display range. The real-time
dynamic range value will be displayed on the image parameter area on the top of the screen.
