Setup
Display Options Sets the loop display options to Manual Display or
Auto Display.
Manual display—Does not display a loop after it has
been acquired. You must manually enter Display mode
by touching the Display control.
Auto display after each acquire—Automatically
enters Display mode after a loop has been acquired,
showing the acquired loop.
Frame Lock Prevents video frames from being generated with
different acoustic data on the even and odd fields. This
touch control is active in CLR or Stress paused mode.
When active, loops are acquired at or below the video
rate (30 Hz in the U.S.A., 25 Hz elsewhere), regardless
of the acoustic frame rate. Eliminates jitter during slow
motion playback. This control has no effect on acoustic
cine acquisitions, which capture loops at the acoustic
rate with no jitters.
Scroll Right When Scroll Right is active, roll the trackball to the
right to see Doppler and MMode data from the period
before the image was frozen. When Scroll Right is
inactive, roll the trackball to the left to see this data.
