4-3-4 System B/M-Mode Checks
For a basic functional check of the system’s different modes,  the Quick Guide will familiarize you with 
image optimization for  B-Mode, M-Mode , Color Flow, and Doppler .
Table 4-2    B/M-Mode Functions
Power Output (Acoustic Power) Optimizes image quality and allows user to reduce beam 
intensity. 2% increments between 0-100%.
Dynamic Range Dynamic Range controls how echo intensities are converted to 
shades of gray, thereby increas
ing 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 corres
ponding to the focal zone 
position(s) appears on the right edge of the image. 
Rejection Selects a level below which ec
hoes 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 
Modes edge enhancement affects the M Mode only.
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 probes next lower
frequency or shift up to a higher 
frequency.
Frame Rate/Resolution Optimizes B Mode frame rate or spatial resolution for the best 
possible image.
B Flow 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 lets you view the anatomy roadmap; 
Background Off lets you view just flow information.
Sweep Speed Changes the speed at which the timeline is swept.

4-3-5 System CFM and PWD Checks 
Table 4-3    CFM and PWD Functions
BaselineAdjusts 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.
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
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. 
Quick Angle Correct Quickly adjusts the angle by 60 degrees
Doppler Display Formats Display layout can be preset to have B-Mode and Time-motion 
side-by-side or over-under.
In the side-by-side layout, there are three display alternatives 
defined: equal priority, time-motion 
priority or time-motion with 
B-Mode reference.
In the over-under layout, there  are three display alternatives 
defined: time-motion priority, B Mode priority or equal priority.
Sample Volume Gate Length Sizes the sample volume gate
Scan Area Slants the B-Mode or Color Flow linear image left or right to get 
more information without moving the probe

4-3-6 Basic Measurements
NOTE: The following instructions assume that you first scan the patient and then press  Freeze.
4-3-6-1 Distance and Tissue Depth Measurements 1.) Press MEASURE
 once an active caliper displays.
2.) To position the active caliper at the start poin t (distance) or the most anterior point (tissue 
depth), move the TRACKBALL
.
3.) To fix the start point, press  Set. The system fixes the first caliper and displays a second active 
caliper.
4.) To position the second active caliper at the end point (distance) or the most posterior point  (tissue depth), move the  TRACKBALL
.
5.) To complete the measurement, press  SET
. The system displays the distance or tissue depth 
value in the measur ement results window.
Before you complete a measurement: 
To toggle between active calipers, press  MEASURE
.
To erase the second caliper and the current data measured and start the measurement again, press 
CLEAR
 once.
NOTE: To rotate through and activate previously fixed calipers, turn  CURSOR SELECT
.
NOTE: After you complete the measurement, to erase all data that has been measured to this point,  but not data entered onto worksheets, press CLEAR
.
4-3-6-2 Circumference/Area (Ellipse) Measurement 1.) Press MEASURE
 once; an active caliper displays.
2.) To position the active caliper, move the  TRACKBALL
.
3.) To fix the start point, press  SET
. The system fixes the first caliper and displays a second active 
caliper.
4.) To position the second caliper, move the  TRACKBALL
.
5.) Turn the  ELLIPSE
 control; an ellipse with an  initial circle shape appears.
NOTE: Be careful not to press the Ellipse co ntrol as this activates the Body Pattern.
6.) To position the ellipse and to size the measured axes (move the calipers), move the  TRACKBALL
.
7.) To increase the size, turn the  ELLIPSE
 control in a clockwise direct ion. To decrease the size, 
turn the ELLIPSE
  control in a counte rclockwise direction.
8.) To toggle between active calipers, press  MEASURE
.
9.) To complete the measurement, press  SET
. The system displays the circumference and area 
in the measurement results window.
Before you complete a measurement: 
- To erase the ellipse and the  current data measured, press  CLEAR
 once. The original caliper 
is displayed to restart the measurement.
- To exit the measurement function without completing the measurement, press  CLEAR
 a 
second time.

4-3-7 Probe/Connectors Usage
4-3-7-1 Connecting a probe
1.) Place the probes carrying case on a stable surface and open the case.
2.) Carefully remove the prob e 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 counterclockwise.
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 co rd holder spot so it is free to move, but not 
resting on the floor. 
4-3-7-2 Activating the probe Select the appropriate probe from the probe indicators on the monitor screen. The probe selection 
screen will be come up when th e application key is enabled. 
The probe activates in the currently-selected operati ng mode. The probes default settings for the mode 
and selected exam are used automatically.
4-3-7-3 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. (refer to the Basic User Manual for  complete probe cleaning instructions.)
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.
4-3-7-4 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.
