Perform the following procedure:
1. Use the [Pan Zoom] on the touch screen, or freeze the image and rotate <Depth/Zoom> knob
to enter the pan zoom status. Image-in-image is displayed.
The image magnification factor value will display in real time in the image parameter area. For
example, “Z 1.40” indicates that the magnification factor is 1.4.
2. Adjust the magnification factor to 1.00 to exit pan zoom.
13.2.3 Spot Zoom
Perform the following procedure:
1. Press <Freeze> to freeze the image and press <Depth/Zoom> knob to light the Zoom indicator.
2. ROI adjustment: press <Set> to switch between size and position status; roll the trackball to
change the size/position. You can also change ROI size by rotating <Depth/Zoom>.
3. Press <Depth/Zoom> / <Update> key to enter Spot Zoom status.
– Rotate the <Depth/Zoom> knob to change the magnification factor.
– Use the trackball and <Set> key to change ROI size and position.
4. Press <Depth/Zoom> or <Freeze> to exit spot zoom.
13.2.4 iZoom (Full-screen Zooming)
Perform the following procedure:

The zooming area includes image area, parameter area, image banner, and so on.
2. Press the user-defined key again to zoom in the image area only.
The image goes to full-screen.
3. Press the user-defined key again to exit.
13.3 Freeze/Unfreeze the Image
Press <Freeze> on the control panel to freeze a scanning image. In freezing mode, the probe stops
transmitting acoustic power, and all images as well as the parameters are kept still.
Press <Freeze> in frozen mode to unfreeze the image, and the system continues image scanning.
Imaging Mode Switching When Frozen
Imaging mode switching in frozen mode follows the following principles:
• In splitting display B mode, press <Dual>/user-defined <Quad> key to switch among the
windows; press <B> to exit splitting display mode and enter the image of the currently
activated window in full screen.
• In frozen mode, the system supports imaging mode switching between the sub-modes (only for
the activated window). For example, if the frozen image is of B+C+PW mode, then the system
supports imaging mode switching between B+C+PW, B+C, B+PW and B by pressing <C> or
<PW>.
• The imaging mode and parameters of an unfrozen image is the same as the corresponding one
that before frozen; but the display format is the same as the one before unfrozen.
