Introduction
The Vivid 7/Vivid 7 PRO ultrasound scanner provides several 
basic scanning modes and several options for combining the 
use of these modes.
The following scanning modes are described in this chapter:
• 2D Mode Imaging
• M-Mode Imaging
•  Anatomical M-Mode (straight and curved)
•  Color Mode Imaging
• Angio
• Doppler Mode Imaging
•  Tissue Velocity Imaging
See page 271 for 
further information 
on image and 
cineloop storage.

2D assignable controls
Width
Controls the size or angular width of the 2D image sector. A 
smaller angle generally produces an image with a higher frame 
rate.
Focus
Changes the location of the focal point(s). A triangular focus 
marker indicates the depth of the focal point.
Frame rate
Adjusts frame rate (FPS). Rotate the knob clockwise to 
increase frame rate. The relative setting of the frame rate is 
displayed in the status...

Cineloop (in Freeze only)
Starts cineloop acquisition.
Gain
When rotated clockwise, increases the overall gain applied to 
the received echo signals equally for all depth.
Time Gain Compensation (TGC)
compensates for depth-related attenuation in an image. The 
sliders nearest the operator affect the far field. TGC amplifies 
returning signals to correct for the attenuation caused by tissue 
at increasing depths.
Depth
Sets the maximum (far...

DDP (Data Dependent Processing)
Performs temporal processing which reduces random noise 
without affecting the motion of significant tissue structures. An 
index number is displayed in the status window (under Proc) to 
indicate the relative DDP level.
Diff On/Off
Affects the level of reverberations in the image. When turned 
on, the frame rate (or the number of focal zones) will decrease, 
while the reverberations will be attenuated.
