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.

Rejection

Frame Average

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

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.

Frequency

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

B Mode Control Panel Controls

Auto Optimize

Automatic Tis sue Optimi zatio n optimizes the image
based upon a specified Region of Interest (ROI) or
anatomy within the display.

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 Zoom
key to activate. Press right zoom key again to
deactivate. Use the Trackball to position the Zoom
ROI.

Reverse

Flips the image left/right.

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

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.

Preparing for an Exam

Frame Rate/Resolution

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

Anatomical M Mode

Allows you to move the M Mode trace in order to
Image difficult -to - reach anatomy.

Sweep Speed

Changes the speed at which the time line is swept.

B/M Mode Image Optimize (continued)

B/M Mode Scanning Hints

Auto Optimize. Improves imaging performance

while reducing optimization time.
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. If you increase the gain, you
may want to decrease the dynamic range.

Edge Enhance. Better delineates the amount of
border crispness.

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

Color Flow/Doppler Image Optimize

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 ind icated on the d isplay.

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

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

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.

Auto Angle

Adjuste the angle to the direction of the Flow.

Angle Steer

Slants the Color Flow region of interest or the
Dopple M Line to obtain a better doppler angle.

Doppler Display Formats

Display layout can be preset to have B-Mode and
Time-motion side-by-side or over-under.

Sample Volume Gate Length

Sizes the sample volume gate.

Map

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

Packet Size

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

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.

Color Flow Control Panel Control

Scan Area

Toggles between the CFM window size and
position.

Controls in Common with B Mode

For more information on Focal Zone, Power Output,
FR/RES, Frame Averaging, Dynamic Range, Map,
and Colorize, refer to the B/M Mode Image
Optimize section in this Quick Guide on Page 6.

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.

1. Increase the Gain.

2. Decrease the PRF.

3. Increase the Power Output.

4. Adjust the Line Density.

5. Decrease the Wall Filter.

6. Increase Frame Averaging.

7. Increase the Packet Size.

8. Reduce the ROI to the smallest reasonable
size.

9. Position the Focal Zones properly.

To decrease motion artifact,

1. Increase the PRF.

2. Increase the Wall Filter.

Threshold

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

Preparing for an Exam

To eliminate aliasing,

1. Increase the PRF.

2. Lower the Baseline.

for A/B ratio or diastole for D/S ratio.

2. The second caliper is the end-point caliper to
the end point of the Doppler waveform. This
would be V
diastole for S/D ratio, “B” velocity for A/B ratio
or systole for D/S ratio.

NOTE: For the PI calculation, if Trace Auto is not
selected, manually trace the waveform between
V

Using Probes

Connecting a probe

1. Place the probe's carrying case on a stable
surface and open the case.

2. Carefully remove the probe and unwrap the
probe cable.

3. DO NOT allow the probe head to hang free.
Impact to the probe head could result in
irreparable damage.

4. Turn the connector locking handle counter
clockwise.

5. Align the connector with the probe port and
carefully push into place.

6. Turn the connector locking handle clockwise to
secure the probe connector.

7. Carefully position the probe cable in the probe
cord holder spot so it is free to move, but not
resting on the floor .

Activating the probe

Press the Probe/Preset button on the front panel.
Move the cursor to the probe icon displayed on the

monitor screen and press SET.
The probe activates in the currently-selected

operating mode. The probe's default settings for the
mode and selected exam are used automatically.

Deactivating the probe

When deactivating the probe, the probe is
automatically placed in standby mode.

1. Press the Freeze key.

2. Gently wipe the excess gel from the face of the
probe.

3. Carefully slide the probe around the right side
of the keyboard, toward the probe holder.
Ensure that the probe is placed gently in the
probe holder.

Disconnecting the probe

Probes can be disconnected at any time. However,
the probe should not be selected as the active
probe.

1. Move the probe locking handle
counterclockwise. Pull the probe and connector
straight out of the probe port.

2. Carefully slide the probe and connector away
from the probe port and around the right side of
the keyboard. Ensure the cable is free.

3.

Be sure that the probe head is clean before
placing the probe in its storage box.
