LGCs (Lateral Gain Controls) Each of the eight sliders adjusts
the amplification of returning signals within a specific
lateral 2D/BMode or AQ image area. Available only
with sector and curvilinear array transducers.
Magnify Increases or decreases the magnification factor of an
image in Zoom or Zoom Preview modes.
Postproc Affects the contrast and brightness of grayscale images
stored in memory, according to visual preference. The
curve you select affects both real-time and frozen
images, but does not affect video playback images.
Secondary
Controls
Switches between the primary and secondary touch
panels. When the control is highlighted, the secondary
controls are active.
Soft Echo
Enhance (Touch
Control)
Activates soft echo enhancement imaging, which may
enhance visualization of low-level ultrasound signals
from normal anatomy and pathology. The Soft Echo
Enhance icon replaces the Frequency Fusion icon and
reflects the setting and the transducer frequency range.
Frequency Fusion and Harmonic Fusion are
unavailable when Soft Echo Enhance is on.
Soft Echo
Enhance (Rotary
Control)
Select the soft echo enhancement setting when Soft
Echo Enhance is on. Settings A to C automatically
adjust transmit power, persistence, dynamic range, and
post-processing to provide increased sensitivity.
Spectral Reformats the screen display to turn a Doppler spectral
trace on or off.
Steering Enables continuous steering of linear grayscale images
to the right or left, to achieve an optimum imaging
angle.
Zoom
Turns zoom (magnification) on or off. To move the
zoom preview area, use the trackball ( is active
when you first enter zoom preview). To resize the zoom
preview area, press and use the trackball. Then
touch Zoom again to enter full zoom mode.
Tip: When activated,
Zoom is first outlined
by a box. This
indicates zoom
preview. Touch Zoom
a second time to go
