In the dual window view, the system displays the M-Mode sample gate image data.
Current data is on the right side, trailing data extends to the left.

Adjusts the cine loop playback speed parameter so that you can stretch out or compress
the cine loop data in the review window. Push up to increase the speed and compress the
cine loop image. Pull down to decrease the speed and expand the cine loop image.
When you are reviewing the cine loop you can also use the
Cine Loop Review
control to
adjust the sweep speed.
In M-Mode: Set the sweep speed parameter in a range from 200 Hz to 4000 Hz in
increments of 100 Hz. The system displays the updated values in the status bar in the
lower left area of the screen.
In cardiac applications you might want to decrease the M-Mode sweep speed so you can
view more wall movements over more cardiac cycles in the window, or increase the
speed so you can view more wall detail over one cycle.
