Imaging modes

The system has a high‐performance display and
advanced image‐optimization technology that
significantly simplifies user controls. Imaging
modes available depend on the transducer and
exam type. See "Imaging modes and exams
available by transducer" on page 34.

WARNING: To avoid incorrect needle
placement when MBe is on:
• Using movement and fluid
injection, verify the needle-tip
location and trajectory. MBe
enhances linear structures within a
selected angle range on the
ultrasound plane. Linear
structures outside the selected
angle range or the ultrasound

• Note that linear structures are
enhanced only in an outlined
portion of the image. The area
outside the outline remains
unchanged. (See
• Note that the beam divergence of
a curved array transducer may
prevent a segment of the needle
shaft from showing in the image.

2D is the systemʹs default imaging mode. The
system displays echoes in two dimensions by
assigning a brightness level based on the echo
signal amplitude. To achieve the best possible
image quality, properly adjust the display
such as a bent

brightness, gain, depth settings, viewing angle,
and exam type. Also, select an optimization
setting that best matches your needs.
To display the 2D image
1 Do any of the following:
• Turn on the system.
• Press the 2 key.

2 Set options as desired. See "2D options."
2D options
In 2D imaging, you can select the following
on‐screen options.
Optimize Settings are as follows:
• Res provides the best possible
resolution.
• Gen provides a balance between
resolution and penetration.
• Pen provides the best possible
penetration.
Some of the parameters optimized
to provide the best image include
focal zones, aperture size, frequency
(center and bandwidth), and
waveform. They cannot be adjusted
by the user.
Dynamic Adjusts the grayscale range: -3, -2,
Range -1, 0, +1, +2, +3.
The positive range increases the
number of grays displayed, and the
negative range decreases the
number of grays displayed.
