B/M-Mode Image Optimize

Power Output

Optimizes image quality and allows user to reduce
beam intensity. 10% increments between 0-100%.
Values greater than 0.1 are displayed.

Dynamic Range

Dynamic Range controls how echo intensities are
converted to shades of gray, thereby increasing the
adjustable range of contrast.

Focus Number and Position

Increases the number of transmit focal zones or
moves the focal zone(s) so that you can tighten up
the beam for a specific area. A graphic caret
corresponding to the focal zone position(s) appears
on the right edge of the image.

NOTE: Push key to toggle between Focus Number
and Focus Position.

Edge Enhance

Edge Enhance brings out subtle tissue differences
and boundaries by enhancing the gray scale
differences corresponding to the edges of
structures. Adjustments to M Mode's edge
enhancement affects the M Mode only.

Colorize

Enables gray scale image colorization. To
deactivate, reselect a Gray Map.

Gray Map

Determines how the echo intensity levels received
are presented as shades of gray.

Rotation (Up/Down)

Rotates the image by selecting the value from the
pop up menu.

Coded Excitation (CE)

B Softener

Affects amount of lateral smoothing.

Suppression

Eliminates low-level echoes associated with
acoustic/electrical noise.

B Flow Image Optimize

Provides intuitive representation of non-quantitative
hemodynamics in vascular structures.

Sensitivity/PRI

Adjusts the sample rate for the flow signal.

Background On/Off

Background On views the anatomy roadmap;
Background Off views flow information only.

Virtual Convex

On Linear and Sector probes, provides a larger field
of view in the far field.

Rejection

Selects a level below which echoes will not be
amplified (an echo must have a certain minimum
amplitude before it will be processed).

Frame Average

Temporal filter that averages frames together. This
has the effect of presenting a smoother, softer
image.

Improves image resolution and
penetration in the far field.

Frequency

Multi Frequency mode lets you
downshift to the probe's next lower
frequency or shift up to a higher
frequency.

Line Density

Optimizes B Mode frame rate or spatial
resolution for the best possible image.

B/M Mode

image difficult-to-reach anatomy.

Sweep Speed

Changes the speed at which the timeline is swept.

Full Timeline

Expands display to full timeline display.

Display Format

Changes the horizontal/vertical display layout
between B-Mode and M-Mode.

between live image.

B/M Mode Scanning Hints

Auto Optimize. Improves imaging performance

while reducing optimization time.

Coded Harmonics. Enhances near field resolution
for improved small parts and OB/GYN imaging as
well as far field penetration.

B Flow. Provides a more intuitive
representation of non-quantitative
hemodynamics in vascular
structure.

Frequency. Changes system parameters to best
optimize for a particular patient type.

Maps. There is an inter-dependency between gray
maps, gain, and dynamic range. If you change a
map, revisit gain and dynamic range settings.

Dynamic Range. Affects the amount of gray scale
information displayed.

Edge Enhance. Better delineates the amount of
border sharpness.

Frame Average. Smooths the image by averaging
frames. Affects the amount of speckle reduction.

Zoom

Magnifies a zoom region of interest, which is
magnified to approximately the size of a full-sized
image. An un-zoomed reference image is displayed
adjacent to the zoom window. The system adjusts
all imaging parameters accordingly. Press to
activate/deactivate; rotate to increase/decrease
zoom factor. Use the Trackball to position the
Zoom ROI.

Color Flow/PW Doppler Image Optimize

Angle Correct

Estimates the flow velocity in a direction at an angle
to the Doppler vector by computing the angle
between the Doppler vector and the flow to be
measured.

Angle Steer/Fine Angle Steer

Angle Steer slants the Color Flow region of interest
or the Doppler M line to obtain a better Doppler
angle. Press Angle Steer to access Fine Angle
Steer. Fine Angle Steer allows you to steer the
Doppler cursor left/right 10 and 20 degrees.
Available from the Doppler Mode Touch Panel.

Baseline

Adjusts the baseline to accommodate faster or
slower blood flows to eliminate aliasing.

PRF/Wall Filter

Velocity scale determines pulse repetition
frequency. If the sample volume gate range
exceeds single gate PRF capability, the system
automatically switches to high PRF mode. Multiple
gates appear, and HPRF is indicated on the display.

Wall Filter insulates the Doppler signal from
excessive noise caused from vessel movement.

NOTE: Push key to toggle between PRF and Wall
Filter.

Threshold

Threshold assigns the gray scale level at which
color information stops.

Map

Allows a specific color map to be selected. After a
selection has been made, the color bar displays the
resultant map.

Invert

Allows blood flow to be viewed from a different
perspective, i.e. red away (negative velocities) and
blue toward (positive velocities). The real-time or
frozen image can be inverted.

Packet Size

Controls the number of samples gathered for a
single color flow vector.

Color Flow/Doppler Mode

Auto Calcs

Specify Auto Calcs Off/Live/Frozen.

Quick Angle

Quickly adjusts the angle by 60 degrees.

Sample Volume Gate Length

Sizes the sample volume gate.

Trace Method

Specify Max, Mean, or Off.

Duplex

Duplex on: simultaneous B-Mode and PW Mode;
Duplex off: toggle live B-Mode and PW via B Pause.

PW/CF Ratio

Adjusts the ratio between Spectral Doppler and
Color Flow.

Compression

Increase to make frozen image appear more
contrasty; decrease to make frozen image appear
softer.

Time Resolution

Lower makes the image appear smoother; higher
makes the image appear sharper.

Color Flow Control Panel Control

Scan Area. Toggles between the CFM ROI window

size and position.

M/D Cursor. Activates the Doppler cursor.

Scanning Hints

Line Density. Trades frame rate for

sensitivity and spatial resolution. If the
frame rate is too slow, reduce the size
of the region of interest, select a different
line density setting, or reduce the packet
size.

Wall Filter. Affects low flow sensitivity
versus motion artifact.

To improve sensitivity. Increase Gain,
decrease PRF, increase Power Output,
adjust Line Density, decrease Wall Filter,
increase Frame Averaging, increase
Packet Size, reduce ROI to the smallest
reasonable size, and position the Focal
Zones properly.

To decrease motion artifact. Increase the PRF,
and increase the Wall Filter.

To eliminate aliasing. Increase the PRF and lower
the Baseline.

For venous imaging. Ensure that you have
selected the vascular exam category, select a
venous application, select the appropriate probe for
very superficial structure, select two focal zones,
adjust the depth to the anatomy to be imaged,
maintain a low gain setting for gray scale, activate
Color Flow, maintain the PRF at a lower setting, and
increase Frame Averaging for more persistence.
