General Imaging Controls
The controls described in this section pertain to all modes, unless otherwise
specified.
Compress Adjusts the dynamic range of returning echoes, thereby
affecting the 2D/BMode or the MMode.
Depth Adjusts the vertical acoustic field of view for the
structure being imaged. Increasing the depth setting
decreases the frame rate.
Focus Repositions the acoustic depth of the 2D/BMode focal
zones, indicated by carets.
Freezes and unfreezes the display.
Frequency Fusion Optimizes frequencies for penetration, texture, or
resolution. Changes are reflected in the Frequency
Fusion icon and on the process line displayed at the top
left corner of the screen.
Gain Adjusts the amplification of received acoustic signals.
Received gain values range from 0 to 100. Used in
2D/BMode and MMode.
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.
In conjunction with the trackball, repositions the active
2D/BMode, Zoom, or color area.
In conjunction with the trackball, resizes the active
area.
Spectral Reformats the screen display to turn a Doppler spectral
trace on or off.
