Imaging Modalities
2D/BMode Imaging
7-34 Revision D.0
Secondary
Adaptive Power Activates 2D imaging with Adaptive Power.
Automatically adjusts transmit power as focus is adjusted.
When Adaptive Power is on, moving the focal carat to the
near field reduces clutter. When multiple focal zones are
active, the power adapts to the deepest focal carat. This
control is unavailable with Curvilinear transducers.
Depth Marks Displays fixed depth marks along the right side of the
image. The MMode/Doppler line is displayed only if
MMode or Doppler is on while depth marks are
displayed.
Edge Enhance Provides increased edge definition in the PW image and
the MMode trace by using the touch controls.
LGC Turns the Lateral Gain Controls on and off.
Persist Adjusts the amount of frame averaging, which can give a
smoother appearance.
Power Adjusts transmit power in decibels (dB) where
0.0dB = maximum power and -30.0dB = minimum power.
Is displayed as part of the primary 2D control set when
contrast is on.
Trapezoid Activates trapezoidal imaging, which widens the linear
image to a trapezoidal shape. Available with linear array
transducers.
U/D Invert Inverts the apex of the sector from its current
orientation. Appears on the right primary touch panel in
cardiac presets and on the secondary touch panel in
noncardiac presets. Also appears on the left touch panel
under the Image controls. Available only with a sector
and curvilinear array transducers.
