Image Width
Adjusts the physical width of the area the transducer is imaging. Push up to
increase the width. Pull down to decrease the width.
Tip: The closer you can reasonably narrow the width of your image around your
target structure, the higher the system sets the acquisition frame rate. This is
especially helpful when you are studying cardiac tissue movement.
Invert
Flips the image.
 In B-Mode: Press to flip the image left/right.
 In M-Mode: In the dual window view, press to flip the B-Mode scout image
left/right.
 In PW Doppler Mode and PW Tissue Doppler Mode in the dual window
view: Press to flip the spectrum window vertically.
 In Color Doppler Mode: Press to flip the image left/right.
 In Power Doppler Mode: Press to flip the image left/right.
 In Contrast Mode: Press to flip the image left/right.
Active during: Image acquisition and review sessions in all imaging Modes
except 3D-Mode.
L/R Screen
Toggles focus from left to right screen when in split screen mode.
Line Density
Adjusts the resolution of your image by adjusting how many lines of image data
the transducer acquires over your image area. Push up to increase the line
density. Pull down to decrease.
The higher you set your line density, the lower the system sets the acquisition
frame rate. Because of this trade off, you might find that higher line density is
most useful for examining features in tissues that don't move very much such as
liver, spleen, pancreas, and prostrate.
For cardiology applications, you will tend to keep the line density lower so you
can increase the frame rate to measure more tissue movements over the time span
of a complete cardiac cycle.
Measure
When in a Mode window, activates the measurement panel.
