6�4 Acquiring M-Mode Images
M mode is generally used with 2D imaging, and is helpful for cardiac applications. In the M mode, you can
position the M line in the 2D image on the anatomy of interest, and then learn about the tissue motion along that
line in M-mode trace. In M-mode, y-axis is used to display the position or depth of the tissue, and x-axis is the time
scale.
6�4�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.

M key on the control panel to enter the inactivated B+M mode.
