Using Image Controls
All of the information in this chapter pertains to real-time imaging Many of the controls and functions
change when you freeze the scan For information on using functions when the scan is frozen, see Adding
Annotations on page 6 and Adding Measurements on page 
On the real-time imaging window:
Touch the scan mode (image control) buttons to select the scan mode (See Imaging Screen (Real-time)
on page )
Touch > to switch the control panel pages to go through the available functions (See Switching

2D Mode Image Controls
Overview
The system delivers 2-dimensional digital imaging using 26-level gray map This scan mode delivers
excellent image uniformity, tissue contrast resolution, and steering flexibility in frequencies from 2 MHz to

Adjusting Gain
Adjust amplification of the returning echoes, which adjusts the amount of echo information displayed in an
image The overall brightness of the image can be elevated, but the noise may also be added to the image
with excessive increase in gain
Touch Gain +/- or flick horizontally on the scan area to adjust the gain value
Adjusting Frequency
Change the scan frequency to obtain higher resolution as frequency increases, or deeper penetration as
frequency decreases
To increase the frequency, touch Res To decrease the frequency, touch Pen
