• Use
the
Focus
control to center the focal point(s) around
the region of interest.
• Use
the
Frequency
(move to higher frequencies) or the
Frame rate
control (move to lower frame rate) to increase
resolution in image
• Use
the
Frequency
(move to lower frequency) to increase
penetration.
• Use
the
Reject
control to reduce noise in the image.
• Use
the
DDP
control to optimize imaging in the blood flow
regions and make a cleaner, less noisy image.
• Use
UD Clarity
(Cardiac) or
UD Speckle reduce
(non-cardiac) to reduce image speckle. Extra care must be
taken to select the optimal Speckle reduction level, as too
much filtering of speckle can mask or obscure desired
image detail.
• Use
Adaptive reject
(Cardiac) to reduce near field haze
and blood pol artifact without diluting tissue appearance of
moving structures.
• Press
Color maps
and select a grey map from the menu on
screen.
The Wide Aperture function may improve image quality by
increasing spatial resolution and signal-to-noise ratio. This
feature involves special processing which allows to improving
the beam focus at large depth by increasing the number of
probe's elements involved in producing the ultrasound beam.
Wide aperture function can not be controlled manually by the
user When using linear or convex probes, the wide aperture
feature may turn on or off automatically, depending on various
scanning settings. In particular it turns on while placing the
focus marker at relatively large depth. Wide aperture
automatically turns off when focus is moved to a shallow
region.
WARNING
Always use the minimum power required to obtain acceptable
images in accordance with applicable guidelines and policies.
