Display & Cine Review
6.1 Image Display

The system supports dual-split and quad-split display format. However, only one window
is active at one time.

6.2 Image Magnification
The system supports three magnifications: spot, pan and iZoom, which can be realized
by different operations through the related keys.
NOTE:
Zooming an image changes the frame rate which tends to change thermal
indices. The position of the focal zones may also change which may cause the
peak intensity to occur at a different location in the acoustic filed. As a result,
the MI may change.
6.2.1 Spot
Procedures:
1. In image scanning mode, press<Zoom> to enter the sample volume definition status.
2. Define the sample volume: roll the trackball to change the box size and position,
press <Set> to toggle between setting the size and position. And after sample
volume is set, press <Zoom> again to enter spot zoom status.
Here, the sampled image is displayed, and meanwhile, image-in-image is displayed.
3. Rotate <Zoom> to adjust the magnification factor. The system provides a zoom
range of 0.8-10. Roll the trackball to move the magnified image.
4. Exit: in spot zooming status, press <Zoom> again or press <Esc> to exit image
magnification.
Tips:
