[2] INSTRUCTIONS FOR USE i
About This Manual
The Instructions for Use consists of two volumes:
[1] Instructions for Use
The [1] Instructions for Use includes both a general overview and a
technical description of the ultrasound imaging system. This manual
contains detailed information on the safety and care of the ultrasound
system and its transducers. A chapter is dedicated to the description of
all system controls. The [1] Instructions for Use also includes the
procedures for system setup and beginning an exam.
[2] Instructions for Use
The [2] Instructions for Use includes procedures for acquiring and
optimizing images. This manual provides procedures for general and
exam-specific measurements and calculations.
The System Reference provides reference information for the ultrasound
imaging system.
ii [2] INSTRUCTIONS FOR USE
Conventions
Conventions used throughout this manual are listed below. Take a moment
to familiarize yourself with these conventions.
Cross-References
This manual provides you information by topic. When additional information
exists within this or other manuals, a reference graphic and the name of the
book is provided in the right column. If the information exists within the
chapter, a cross-reference to the page number is listed. Otherwise,
information is referenced by chapter number.
System Presets
You can use the options and settings available in the system presets menu
to set up the ultrasound system with your preferences. Presets define the
configuration of the system software whenever you power on the system.
A complete listing of system presets is located in the System Reference.
Whenever a system preset is discussed in other chapters or in the User and
Reference Manuals, a graphic is provided in the right column.
The graphic identifies a preset option or setting in the system presets menu

Activating Split Mode
Split mode creates side-by-side images from one 2D-mode image. The two
images are simultaneously frozen or real-time. Split mode is available with
all transducers.
When you first initiate Split mode, the image parameter settings from the
previous mode are applied to both images. Certain imaging parameters
(such as Gray Map, A-mode, Reject, and Modify Map) can be changed in
the right image, allowing comparison of the effects of different image
settings on an anatomical structure.

A2 2D-Mode and M-Mode Imaging Functions
2D/M-Mode Display and Update
Curved array and linear array transducers allow a 2D-mode image and an
M-mode sweep to display simultaneously in real-time.
To activate M-mode, 2D/M-mode, or Split/M-mode:
Prerequisite: For Split/M-mode, you must use the system presets to select either the
1/3 – 2/3 or ½ – ½ display format.
1. Press the M key on the control panel.
Note: If the cursor bypass is selected in the system presets, the system activates
2D/M-mode immediately; proceed to step 4. If the cursor bypass is not selected,
the system initially displays an M cursor on the 2D-mode image.
The M
cursor
is a graphical representation of the acoustic line along
which M-mode information is gathered.
2. Roll the trackball to position the M cursor.
3. To activate 2D/M-mode, press the M key a second time.
The system displays a 2D-mode image and an M-mode sweep in the
format selected in the system presets. Use the trackball to reposition the
M-mode cursor on the 2D-mode image.
4. To activate Split/M-mode, first activate 2D/M-mode and then press the
SPLIT key on the control panel.
The system displays two 2D-mode images with the M-mode sweep.
5. To display a full-screen M-mode sweep, display the M-mode Imaging
menu, roll the trackball to Full M and then press the SET key to toggle
Full M with 2D/M.
Note: While a 2D/M-mode display is in freeze, you can press the left
DUAL/SELECT key to toggle a full-screen 2D-mode display on or off, and you can
press the right DUAL/SELECT key to toggle a full-screen M-mode display on or off.

Changing the M-Mode Sweep
You can adjust the scrolling speed of the M-mode sweep, activate time
markers on the sweep, and specify sweep offset.
Scrolling Speed
You can choose from four sweep speeds: 2sec, 4sec, 8sec, and 16sec.
The sweep rate displays in the lower left of the sweep.
The sweep scrolls from the left of the image screen to the right.
To adjust the scrolling speed of the M-mode sweep:
1. Display the M-mode Imaging menu.
2. Roll the trackball to Sweep Sp.
3. Rotate the SELECT control or press the SET key to adjust the setting.
4. Continue adjusting imaging parameters and then press the MENU key
to exit the menu.
Time Markers
Time markers are available for display in the M-mode sweep. Use the
system presets to activate the markers. The vertical markers display in
intervals in a fixed location on the sweep.
Offset
In 2D/M-mode with a 1/3-2/3 or 1/2-1/2 horizontal sweep, you can offset
the 2D-mode image and the M-mode sweep to display specific information
more fully on-screen.
