6.3 Acquiring M-Mode Images
M mode is generally used with B mode imaging, and is helpful for cardiac applications. In
the M mode, you can position the M line in the B mode image on the anatomy of interest,
and then learn about the tissue motion along that line in M-mode trace. In the M-mode,
y-axis is used to display the position or depth of the tissue, and x-axis is the time scale.
6.3.1 M Mode
The M line can be only positioned 90° within the ultrasound beam. Therefore, the M mode
is used to view motion patterns for regular objects.
Perform the following steps to acquire M-mode images.
1. Optimize a B-mode image.
2. Press the M key on the control panel to enter the inactivated B+M mode.
