Working with the Image
To adjust and work with the image (for example, to resize the image or to make a
measurement), you can usually use the trackball keys to point and click and drag. In
some cases (for example, to freeze the image), you can use special keys on the
control panel. For more information about using the trackball and other keys, please
see Chapter 3, “The User Interface”.
Image Orientation
You can change the horizontal or vertical orientation of a 2D image. The view must
be scanning when you change orientation.
To change Left/Right or Up/Down orientation:
•
Click L/R or U/D under Image on the right side of the screen.
The images of all modes in the selected view are inverted horizontally or
vertically.
NOTE:
When you change image orientation, you may need to adjust the TGC
settings for the B-mode image. See “TGC” on page 121
Freezing the Image
To freeze the image, press
[

]
or click Freeze. (You can also use the button on the
transducer itself – see the transducer user guide for information about this.)
All images on the screen are frozen.
If you press
[
p
]
again, the image returns to its previous state.
NOTE: When you freeze the image, the date and time displayed on the screen
are also frozen, so the time displayed on a printed image is the time the image
was frozen, not the time it was printed.
Update - Partial Freeze
Partial freeze is something you can do only when you are scanning in Doppler mode
as well as one or more 2D modes (B-mode, color and power). Partial freeze lets you
freeze only the Doppler image or only the 2D-mode image.
To start partial freeze:
•
Press
