M Mode

M mode imaging provides Time and Motion echo information derived from a stationary ultrasound
beam. M mode is used along with a 2D image. A straight line running through the 2D image, called
the M-cursor, identifies the position of the stationary ultrasound beam from which the echo
information is being gathered. The motion or change that occurs at this position over time is used by
the system to generate the scrolling M mode display.
M mode is primarily a cardiology mode. M mode records moving anatomical structures and produces
subtle patterns of motion. These patterns allow you to plot temporal relationship between events in the
cardiac cycle. Precise measurements of structures are possible with M mode. M mode also provides
textural information that permits discriminating between normal and abnormal tissue.
The M mode display contains system information, a depth scale, a time scale, a TGC curve, and a gray
map pattern. There are three M mode display format options; review:
The continuous update of the M mode display allows you immediately to recognize changes in
anatomical position relative to the M-cursor. With this instant information you can immediately aim
the M-line to the structures of interest by adjusting the probe.
The description of M mode is subdivided in two groups. In these groups you will see how to use
M mode and how to adjust the M mode settings.
