Click [

] to open the menu with the following options:
Transmit Power
Controls the maximum acoustic output of
the transducer. Settings range from 5% to 100% of maximum
and are displayed as Low, Medium, and High. Use the lowest
setting consistent with diagnostic quality. The current
mechanical index (
MI
) and thermal index (
TI
) of the acoustic
output setting are displayed with the System Data.
NOTE: Refer to the “Safety, Standards, and Accuracy” section of this
manual, and the AIUM document provided with your system “Medi-
cal Ultrasound Safety” for important information about Acoustic Out-
put.
Lateral Gain
Select from three preset lateral gain curves.
The lateral gain pre-sets increase the gain along the edges of
the 2D sector. Curve 3 provides the most lateral gain.
Post Processing
Select from seven post processing or
grayscale compression curves. The number 2 selection is a
linear setting.
Colorize
Applies a variety of colorized maps overlaying the
grayshade image. Colorize is useful in certain situations to
optimize contrast resolution.
Structure Persistence
Turns image persistence to Low,
Medium, or High. The default setting depends on the probe.
The higher the setting, the smoother the image.
Left-Right Invert
Switches the orientation of the image from
left to right. When Left-Right Invert is
OFF
, an index marker
appears near the top of the sector on the right side.
Angle
Reduces or increases the sector scan angle. For the
77° sector angle, select either
Angle 1
for 45 fps (frames per
second) or
Angle 2
for 33 fps; a 90° angle is automatically set
to 33 fps (select
Angle 3
).
NOTE: A higher frame rate requires more machine memory and cre-
ates larger studies. Thus, 45 fps uses more memory than 33 fps.
Studies created with higher frame rates require more time to archive
and allow for fewer studies to be archived on the removable disk.
