Filter Removes low-level signals and reduces noise in the
image. It is recommended that you use Filter T with
turbulence maps only.
Focus Repositions the acoustic depth of the color focal zone.
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 system sensitivity to received color flow
signals. Increasing the color gain percentage increases
the amount of color displayed.
L/R Invert Switches the left/right orientation of the image.

presets and on the right primary touch panel in
noncardiac presets. Also appears on the left touch panel
under the Image controls.

image in Zoom or Zoom Preview modes.
Map Invert Switches between the BART (Blue Away, Red Toward)
and RABT (Red Away, Blue Toward) color map
conventions.
Pan When Zoom is on (fully highlighted), enables the
trackball to move the zoom/color box area over the
image.
Scale Changes the range of color flow velocities. Lower the
scale to see slow flow, and increase it to see higher
velocities.
Secondary
Controls
Switches between the primary and secondary touch
panels. When the control is highlighted, the secondary
controls are active.
Spectral Reformats the screen display to turn a Doppler spectral
trace on or off.
