6 Image Acquisition
Dynamic Range (Dyn Ra.)
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.
M Soften
This feature is used to process the scan lines of M images to reject noise, making the image details
to be clearer.
6.7 Color M Mode (CM)
To know the cardiac motion state, CM is overlaid with flow based on M mode, which is more
sensitive to the instantaneous signal changes. Then, it shows the diagnosis information in detail.
The Color M mode includes Color Flow M mode and Color Tissue M mode.
• Linear probe does not support Color M mode.
• Only phased probe supports color tissue M mode.
6.7.1 CM Image Scanning
Perform the following procedure:
1. To enter Color Flow M mode:
– In B+M mode, press <C>.
– In B+Color, press <M>.
2. To enter Color Tissue M mode:
– Press <TDI>, or tap [TDI] on the touch screen, and then press <M> or <Update>.
– In B+TVI/TVD, or B+TVI+TVD mode, press <M>.
3. Adjust the image parameters to obtain optimized images.
4. Exit Color M Mode
Press <C> or <M> on the control panel to exit Color M mode.
Or, press <B> on the control panel to return to B mode.
6.7.2 CM Image Parameters
In Color Flow M mode, parameters that can be adjusted are in accordance with those in B, M and
Color modes; please refer to relevant sections of B, Color and M mode for details.
In color tissue M mode, parameters that can be adjusted are in accordance with those in B, M and
Color modes; please refer to relevant sections of B, Color and M mode for details.
The ROI size and position determine the size and position of the color flow displayed in the color
M mode image.
• Set the position of the sampling line by moving the trackball left and right.
• Press <Set> to switch the cursor status between the ROI position adjustment and ROI size
adjustment.
