4-3-4 Basic Controls
4-3-4-1 Introduction  Most of the mode dependant controls can be foun d as Mode Dependant Keys (Mode Dependant Rotary 
Knobs and Mode Dependant Push Buttons) and Trackball. The functions available on the Mode 
Dependant Keys and Trackball vary according to the  scan mode and position that is currently active.
4-3-4-2 Mode Dependant Rotary Knobs Vivid 7 has four mode dependant rotary knobs. The  assigned functions are indicated above the rotary 
on the LCD display. 
4-3-4-3 Mode Dependant Push Buttons Vivid 7 has five Mode Dependant Push Buttons. The  assigned functions are indicated above the button 
on the LCD display.
4-3-4-4 More The MORE
 button gives access to additional contro ls on the Mode Dependant Push Buttons.

4-3-4-5 Soft Menu Control (4-way Rocker) The 4-way Rocker works together with the Soft menu on the screen.
• The vertical arrows (up/down) are used  to do selections from the Soft Menu.
• The horizontal arrows (left/right) are used  to do adjustments on the selected function.
4-3-4-6 Trackball Area Different functions can be assigned to the trackball  depending of the current active mode. The Trackball 
area consist of:
• The Trackball: used as a cursor control in acqu isition mode, scrolling control in freeze and as a 
selection tool (like a mouse cursor) in post-processing mode.
• Three 
SELECT keys (identical): Perform the select ed control or highlighted menu item.
•The 
TRACKBALL key: Toggles between the available trackball function assignments displayed in 
the Status bar.
• The update menu key: enables quick access to  image related functions from a pop-up menu.
4-3-4-7 Other Controls Other controls are located on separate keys (knobs a nd buttons) or groups of keys on the Operator 
Panel.

4-3-5 Performance Tests
4-3-5-1 Recommended Test Phantoms GE Healthcare recommends the RMI 430GS phantom. It  is the most current phantom recommended to 
our field service personnel and provides the necessary targets and extended life necessary for 
consistent system testing.

4-3-6 2D Mode (B mode) Checks
4-3-6-1 Introduction The 2D Mode is the system’s default mode.
4-3-6-2 Preparations Use a phantom when doing these tests.
1.) Connect one of the probes, to the scanner’s left-most active probe connector. -See  Probe Connection on page 3-21  for info about connecting the probes.
- See section  Section 9-26 Probes on page 9-80  for available probes.
2.) Turn ON the scanner. -See  4-2-2 Power ON/ Boot UP on page 4-3  for info about booting the scanner.
The 2D Mode window is displayed (default mode).
3.) If needed, adjust the Display’s  Brightness and Contrast setting.

4-3-6-2      Preparations (cont’d) 4.) Press 2D on the Operator Panel to access 2D Mode.
5.) These Image Controls are used  to optimize the 2D picture:
-Use  Gain and  TGC controls to optimize the ov erall image together with the  Power control.
-Use  Depth to adjust the range to be imaged.
-Use  Focus to center the focal point(s) around the region of interest.
-Use  Frequency  (move to higher frequencies) or  Frame rate (move to lower frame rate) to 
increase resolution in image.
-Use  Frequency  (move to lower frequency) to increase penetration.
-Use the  DDP control to optimize imaging in the blood flow regions and make a cleaner, less 
noisy image.
-Use  Reject/Adaptive Reject  controls to reduce noise in the image.
-Use the  UD Clarity control to personalized appearance of  the tissue. Moving the paddle to 
the left creates a smoother image, though ke eping boundaries sharp. Moving the paddle to 
the right creates a crisper image.

4-3-6-3 Check Width, Focus, Framerate, Frequency These 2D Mode Functions are located on Mode Dependant Rotaries. 
The results of these adjustments must be verified on the 2D sector on the screen. 
  Table 4-6    2D Mode: Check Width, Focus, Framerate and Frequency
StepTaskExpected Result
1.Turn the rotary labeled  WIDTH left and right.
Controls the size or angular width of the 2D image 
sector. 
A smaller angle generally produces a scan with higher 
frame rate.
2. Turn the rotary labeled  FOCUS
 left and right to move 
the focal point up and down.  Changes the location of the focal point(s).
A triangular focus marker indicates the depth of the 
focal point. 
3. Turn the rotary labeled  FRAMERATE
 left and right to 
adjust the Frame Rate  Adjusts frame rate. 
Rotate the knob clockwise to increase frame rate. 
The relative setting of the frame rate is displayed in the 
status window. 
When adjusting frame rate, there is a trade off between 
spatial and temporal resolution.
4.Turn the rotary labeled 
FREQUENCY left and right to 
verify that the probe’s operating frequency can be 
adjusted Enables the adjustment of the probe’s operating 
frequency. 
Rotate the knob clockwise to increase the frequency.
The selected frequency is displayed in the status 
window. 
For some probes/applications, the lowest frequency 
settings will be Octave Imaging settings.

1. Adjust  TISSUE GAIN
Increases the overall gain equally for all depth when 
rotated clockwise
2. Adjust Time Gain Compensation (TGC) Compensates for depth-related attenuation in an 
image. 
The upper sliders affect the near field.
The lower sliders (nearest the operator) affect the far 
field. 
3. Adjust Depth Sets the maximum (far field) distance that will be
