5.4 M Mode Image Optimization
5.4.1 M Mode Exam Protocol
1. Select a high-quality image during B mode scanning, and adjust to place the area of
interest in the center of the B mode image.
2. Press <M> on the control panel, and roll the trackball 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.
5. Perform other operations (e.g. measurement and calculation) if necessary.
 If you choose "Enter 1D Mode Directly" in "[Setup]→[Image Preset]→[Other]", then
the sampling line will be displayed at all times in B mode images, and pressing <M>
will directly enter M mode.
