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.

the size and position, or rotate the <Zoom> knob to adjust the size. After the sample volume is
